PURPOSE: To detail the procedures used for set-up and final preparation of Almax fiberglass-composite resin long-term patient care cryostats. This standard operating procedure (SOP) (aka Best Practices) details the vendors, materials and techniques used to prepare the Almax cryostats for full operational status after receipt from the manufacturer.

1.0. Detail of configuration and a brief overview of the manufacturing procedure used to produce cryostats.

Almax cryostats are cylindrical, double walled vessels that employ perlite and low vacuum (1-12 torr) insulation to facilitate highly efficient long-term liquid nitrogen refrigeration of cryopatients. Each unit has an overall height of 327.7 cm, an external diameter of 182.9 cm, an internal diameter of 121.9 cm and a useable internal height of 218.4 cm. The static liquid nitrogen capacity of Almax cryostats is approximately 2550 liters with a static boil-off rate in the range of 10.5 to 12.5 liters per day. Adult, human, whole body patient capacity is between 4 and 6 patients, depending upon patient diameter and the method of packaging used.

1.2.  Engineering details are presented Figure 1.1-1.2.

Figure 1.1: Detailed engineering specifications for the Almax long-term patient care Cryostats.

The cryostats are fabricated from a fibreglass mat-modified vinyl ester (Hetron 922, Ashland Chemical Co.) composite. The basic procedure for fabrication consists of building up layers of glass mat saturated with a resin monomer that is reinforced with carboxyl-terminated butadiene-acrylonitrile copolymer. The resin is polymerized (cured) using methyl ethyl ketone peroxide (2-butanone peroxide, or MEK-peroxide), which initiates free-radical cross-linkage of the monomer. This technique avoids incorporation of the MEK peroxide catalyst into the finished polymer, rendering it more stable, more corrosion resistant and less chemically reactive. Five millilitres of MEK peroxide are used per pound of Hetron 922. The inner vessel (can) of the cryostat is an open- topped cylinder with a concave bottom made from of vinyl ester resin and glass mat with a wall thickness of ~13 mm. The outer cylinder (can) is comprised of the same material, has a wall thickness of ~15 mm and is connected to the inner can only by a glue bond where the two are joined at the opening of the inner can on the top of the cryostat.

The opening of each cryostat is closed with a snug-fitting insulating neck-plug with an external cover of 14 gauge grade #2, 304 stainless steel. The insulating neck-plug is made from 22 layers of 2.5 cm thick Owens-Corning high density extruded polystyrene insulating foam board (~121.9 cm in diameter by 55.9 cm thick.) which are sandwiched between the stainless steel cover and an inner cover of painted chip board or marine plywood using 4 threaded nylon rods to compress and secure the foam to the inner and outer covers of the cryostat lid. A section of 5.1 cm diameter PVC plastic pipe penetrates the neck-plug and external cover in the center allowing access to the inside of the cryostat for temperature and liquid level monitoring.

Figure 1.4: Removal of cryostat from shipping vehicle/container.

1.4  Atmospheric air is withdrawn from the annular space of the cryostat in order to create a vacuum in two stages. The first stage employs a roughing pump which is capable of reducing pressure in the annulus to ~ 5 x 10-2 torr, however it will only be necessary to achieve a stable vacuum of ~ 500 torr before switching to the polishing/ maintenance vacuum pump. The roughing pump used is  in an Alcatel ACP-15, 8.2 cubic ft/min with a peak pumping speed of 14 m3 /hr and a final vacuum capacity of 5 x 10-2 torr. The ACP-15 employs Roots blower technology. Roots pumps are positive displacement machines using two synchronized rotors rotating in opposite directions. The rotors feature profiles usually shaped like the figure 8.During the rotation, molecules of gas are isolated between the lobes and the stator and then led to the exhaust side of the pump without variation of volume.


Figure 1.5: Alcatel ACP-15 roughing pump.

The ACP-15 features a frictionless pumping module that is optimized for operation without internal lubrication. Complete technical specifications, operation and servicing instructions for the ACP-15 are present as Appendix 1 to this SOP.

Figure 1.6: Welch 1376C-03, DUOSEAL®, two-stage, belt drive high vacuum pump.

Final ‘polishing’ evacuation of the cryostat annulus as well as maintenance of the vacuum, is achieved using a Welch 1376C-03,DUOSEAL®, two-stage, belt drive high vacuum pump. The Welch pump has a peak pumping capacity of 300 LPM (10.6 CFM) with a final achievable vacuum of 1 x10-4 torr. The Welch pump motor is configured to operate on 220V, 50 Hz,1 PH and is supplied with Schuko plug which must be replaced with a ____________ plug prior to be being placed into service.

Complete technical specifications, operating and servicing instructions for the Welch Welch 1376C-03,DUOSEAL® pump are present as Appendix II to this SOP.

2.0.  Shipment and unloading of the cryostat.

2.1.  The cryostats is palletized and prepared for shipment via commercial freighter in a sea-land container. It is then shipped, either by semi-trailer, or by truck, within the sea-land container, on wooden skids (generally skids of very poor quality). Drag chains are placed around the skids and they are pulled to the end of the trailer. Then they are pulled out further with the forklift so that the rear end of the skid rests firmly on the trailer and the opposite end of the skid is then lowered to rest on a wooden support frame so that the pallet holding the cryostat can be can be picked-up from the side with the forklift, removed from the  truck and moved into the facility where the cryostat is placed on custom made steel frame castered trolley for additional preparation, prior to placement into service.

Figure 2.2: The forklift is repositioned at the side of the cryostat/pallet and the unit is removed from the vehicle and placed on the ground..

 Figure 2.3: The evacuation port cover plate used to hold perlite in place and prevent contamination of the perlite with moisture during shipping is unbolted and removed.

 Table 2.1: Equipment, Tools and Supplies Required to Remove Cryostats from Delivery Vehicle

Item Description Quantity & Specifications
Steel drag chain Promac WD-113 or higher:
S- hooks 2,500 kg load (minimum)
Wooden support frame 10.2 cm x 10.2 cm x X cm X cm X cm
Snug fitting pig skin leather work gloves Size required by personnel
Forklift with long tines 5,000 kg load capacity
Metal shears To cut securing tie bands

2.2.  The cryostat is shipped from the manufacturer with a resin-composite cover plate and sealing gasket secured to the evacuation port opening of the unit with 12 bolts (Figure 1.3). This cover plate serves both to contain the perlite insulation material and keep it dry during shipment. Perlite is moderately hygroscopic and will absorb water from the atmosphere in high humidity environments. Once the cryostat is in the storage facility, the cover plate is unbolted and the cover plate and the neoprene rubber gasket that seals it to the evacuation port flange are removed and set aside. The evacuation port opening is then immediately covered with a heavy-duty, 3 mil plastic refuse bag that is tightly secured in place with a ratchet-type nylon tie-down strap. It is important to immediately and tightly cover this opening to prevent moisture from entering the annular space and contaminating the perlite, since this would make subsequent evacuation of the annulus difficult, or impossible.

  Figure 2.4:  A custom built trolley fabricated from powder coated welded steel tube stock and high quality 3″ diameter urethane casters is used to safely move the  cryostat around the facility in the horizontal position during post -manufacturing preparation. Wooden skids are used to protect the cryostat from damage by the steel frame of the trolley.

 2.3.  The cryostat is transported to the work-area at the facility by placing it on a custom built metal trolley. The unit is left on the trolley until all preparative work (prior to hoisting the unit into the upright position) is completed.

3.0 Topping up the cryostat with perlite.

3.1 Protective clothing consisting of a heavy-duty, hooded Tyvek work coverall, fabric reinforced vinyl gloves and a full face N-100 respirator are donned. Duct tape is used to secure the hood opening of the of Tyvek suit to the edges of the respirator, the sleeves of the Tyvek suit to the work gloves and the tops of the work boots to the leggings of the Tyvek coverall, as shown in Figure 3.1, below. It is important to achieve a seal at all joints in the protective clothing in order to prevent the highly irritating perlite dust from contaminating the worker’s skin.

3.2  The plastic bag covering the evacuation port is removed and perlite is poured from the bags into the evacuation port opening as shown in Figure 3.2. The perlite is spread out inside the annular space and packed tight with wooden spreading and tamping paddles that are made in-house, as shown in Figure 3.3, below. Considerable force is required to tamp the perlite solidly into place, and typically the full weight of the worker must be brought to bear on the tamping paddle.

Figure 3.1: Duct tape is used to secure and seal the respirator, gloves and boots to the protective Tyvek coverall in order to prevent perlite dust from coming into contact with the workers’ skin. An full-face N-100 respirator is to provide respiratory protection from the perlite dust. Note perlite spreading and tamping tools resting on the cryostat at the middle left of the photo.

 Figure 3.2: Perlite is poured from the 20 lb bags into the cryostat annular space with the workman standing atop the cryostat.

Figure 3.3: A spreading and tamping tool are fabricated from plywood and a 24 x 24 x 61 cm piece of lumber (which serves as the handle). The spreading tool has the handle offset to one side of the plywood plate, while the tamping tool has the handle secured to the center of the plate allowing for stability and even distribution of load when compressing the perlite. The handles are secured to the plywood plates using  1/4″  by 3″ wood screws reinforced with quick-set epoxy adhesive.


Figure 3.5: Perlite is tamped into place in the annulus of the cryostat using the wooden tamping tool.

Figure 3.6: When the annular space is filled with packed perlite to the level of the bottom of the evacuation port no additional perlite is added and the top of the cryostat is brushed off with a household broom.

Figure 3.7: The evacuation port is again tightly covered with a plastic bag to prevent entry of water vapor into the annular space.

Figure 3.8: A jet of compressed air is used to clean the perlite dust off of the cryostat.

4.0.  Preparation of the evacuation port and evacuation valve assembly.

The first step in preparing the evacuation plumbing assembly is to sweat solder a 27 cm long x 3/4″ piece of copper onto a 3/4″ NPT Stainless Steel Ball Valve Full Port WOG1000 SS304 SUS304 0.75 .75 Female Ports.

Assemble the tools and supplies required for sweating the section of pipe into the valve. Prepare the copper pipe by sanding both ends using fine grit sand paper. Apply solder paste to the end to be sweated to the ball valve and insert the pipe into the 3/4″ copper T-connector. Don gloves and heat the copper pipe and connector with the torch for approximately 30 seconds. Apply solder by touching a J-shaped piece of solder to the joint 7 times; the solder will be drawn into the joint between the pipe and connector by capillary action. If the metal is not hot enough, reheat it with the torch as necessary. Allow the solder to cool and set-up for 60 seconds and then wipe the joint clean with a shop towel. Any remaining excess solder may be removed with a wire brush.

The threaded copper NPT to pipe slip fitting is then attached to the vacuum shut-off valve using Teflon thread sealing tape to insure a gas-tight seal.

Table 4.1 Tools and Supplies Required for Sweating Joints in Copper Pipe


Item Description Quantity
Copper Pipe 1 ea  3/4″ x 27.9 cm
Pipe cutter 1 ea
Pipe cleaner & de-burrer 1 ea
Solder paste 1 tube, 3 ounces
Solder Silver solder (non rosin core)
Mapp gas or propane gas torch 1 ea
Gloves 1 pair, close-fitting work gloves
Teflon plumber’s sealing tape 1 roll


Figure 4.1: A section of copper pipe is sweat-soldered into the female end of a brass NPT connector which is then screw threaded into a ball type shut off valve using Teflon pipe joint sealing tape.



The valve and pipe assembly are then attached to the evacuation port cover plate by drilling a hole just large enough to admit the copper pipe in the center of the 41.9 cm diameter cover plate. It is important that the hole be a tight fit to the valve and pipe assembly so that the pipe can be securely cemented into place without any possibility of leaks (there must be a gas-tight seal). The copper pipe is prepared for cementing into place by sanding with fine grit sand paper, after which it is degreased using acetone and a clean rag (or lint-less disposable shop towel). The end of the pipe to be attached to the evacuation port cover is then painted with Special Blend MFR-10 lb laminating resin (low volatile organ compound, mixed 100 to1 with methyl ethyl ketone (MEK) peroxide (supplied by Michigan Fiberglass Sales, St. Claire Shores, MI)  and the pipe is inserted into the previously drilled hole. Additional coats of laminating resin and glass mat, as needed, are used to secure the evacuation pipe in place, with care being taken to ensure that the pipe opening remains clean and unobstructed by resin. Each coat of applied resin is allowed to fully cure before the next coat is applied.

Figure 4.2: Top: the evacuation port cover plate with the stub of copper pipe to which the vacuum valve will be attached already in position. Bottom: schematic of the evacuation port, vacuum valve and T assembly housing the thermocouple vacuum gauge.

The back of evacuation port cover plate and the tip of the copper evacuation pipe assembly is then prepared for bonding to the flange of the evacuation port by being sanded with fine grit sandpaper. Once the plate has been “roughed-up” so that the adhesive epoxy will adhere, it is blown clean of particulates with a jet of compressed air, and then wiped with a clean rag dampened with acetone. Seven 6”x6” squares of cotton batting for filtration are painted with special blend MFR-10 lb laminating resin, low V.O.C. mixed  100/1 with MEK Peroxide (both from Michigan Fiber Glass Sales, St. Claire Shores) for hardening and adhesion.

Figure 4.3: Cotton batting filter pads are shown being cemented in place on back of evacuation port cover plate.

Figure 4.4.: The edges of the cotton bats are saturated with adhesive resin and smoothed onto the back of evacuation port cover plate.

The neoprene rubber gaskets that were between the evacuation port cover plates and the evacuation port flanges during shipment from Almax are used as templates for cutting the 3/4 ounce chopped strand FG-03438 fiberglass cloth rings.

Figure 4.5: The rubber sealing gaskets used to protect the annulus from the ingress of dirt and moisture during transport of the cryostat from the manufacturer are used as templates for cutting rings of fiberglass cloth which will act as the permanent sealing gasket.

Figure 4.6: It is important to wear respiratory protection whenever working with or around fiberglass. N-95 masks are suitable for such work, whereas a full-face N-100 respirator is required for work where perlite dust is being generated.


The fiberglass cloth rings are then applied to the cryostat evacuation plate flange using the same laminating resin that was used to adhere the cotton filter pads.

Figure 4.7: This illustrates proper preparation for cementing the fiberglass cloth rings to the evacuation port plate flange. Note the presence of a piece of protective (black) plastic to prevent damage or marring of the surface of the cryostat with the resin being used to cement the rings in place.

Figure 4.8: Household fiberglass building insulation (Owens-Corning) is used to plug the opening of the evacuation port. This prevents the perlite from migrating into the vacuum line, and it also serves as a coarse pre-filter for the larger particles of perlite dust, preventing them from entering the vacuum pumps.

Owens-Corning fiberglass “wool”  building insulating is packed against the perlite to prevent the perlite from plugging the filter.  The edges are then painted with laminating resin to facilitate adherence of the fiberglass cloth rings.

Figure 4.9: The edges of the evacuation port flange are carefully painted with resin to insure adhesion of the fiberglass cloth rings and to facilitate a thorough seal when the port cover is applied and clamped in place for final bonding to the flange.


 4.10: A small paint application roller is used to evenly apply (and assure saturation of) the fiberglass cloth rings to the flange.

A roller applicator is used to apply more laminating resin to the fiberglass cloth  rings. Three fiberglass “cloth” rings are applied in this manner to each cryostat. [The non-disposable parts of the roller may be cleaned up with acetone after use.] Once preparation of the fiberglass cloth rings is completed, the back surface of the evacuation port cover plate is painted with resin, taking care not to contaminate the cotton batting filters.

Figure 4.11: After the prep of the filter is completed and the final coat of adhesive has been applied, the back of the evacuation port cover plate is carefully and completely painted with adhesive resin taking care not to get resin on the cotton filter pads.

Figure 4.12: The evacuation port cover is then attached to the flange and held in place tightly with 4 equidistantly spaced C-clamps which are left in place until the resin has dried and fully hardened (~72 hours under normal working conditions).

The evacuation port cover with its integral filter (i.e., glued-on assembly of 3 cotton bats) is then clamped onto the flange opening and held in position for the adhesive resin to set up and cure.

5.0 Initial (rough) evacuation of the cryostat

 Initial evacuation of the cryostat is undertaken using the Alcatel ACP-15 roughing pump to a stable vacuum of ~ 500 torr. The Welch 1376C-03,DUOSEAL®, two-stage, belt drive high vacuum pump. must not be used for initial evacuation of the cryostat.  Failure to pre-evacuate the cryostat using a roughing pump will result in contamination of the oil in the two-stage pump with water and can damage the pump mechanism. Additionally, two-stage vacuum pumps are not designed to pump high density atmospheric gas – they are to be used only as “polishing” pumps to  harden and subsequently maintain the vacuum to ~ 1.0 torr.

Figure 5.1: Initial evacuation of the perlite filled annulus is accomplished using the Alcatel roughing pump. An inexpensive Bourdon tube vacuum  gauge (VG350-14CBM) is interposed in the vacuum line (mounted on a 3/4″ copper T-connector) to monitor the progress of the initial pump-out.

Figure 5.2: Once a vacuum of ~ 1.0 torr is achieved, the vacuum valve is closed, the roughing pump is removed, and the 2-stage vacuum pump is connected to the annulus. For this preliminary hardening of the vacuum a thermocouple vacuum gauge is used and is placed near the pump, for convenience.

 6.0 Preparing the base of the cryostat prior to erection upright.

A five foot diameter circle of 3/4″ plywood is used to seal and secure the bottom of the cryostat. The plywood circle has three 5″diameter holes cut in it, arranged as shown in Figure 6.1, to allow for 2-part  urethane foam resin to be poured into the space between the plywood circles and the bottom of the cryostat. Once the urethane resin foams, expands and sets, it serves to stabilize and reinforce the plywood so the bottom of the cryostat and ensure that  it is well supported and stable on the floor when the unit is finally filled with liquid nitrogen.

Figure 6.1:Circles of 3/4″ plywood are cut so as to fit into the opening of the base of the cryostat’s outer cylinder. Three 5″ diameter holes, spaced equidistant from each other are cut into the plywood to allow for filling of the space between the plywood discs and the bottom of the cryostat with urethane foam. The discs are placed with the holes at the top of cryostat base so that the urethane resin-activator mixture does not leak out onto the floor during loading into the base of the cryostat.

 Figure 6.2: The plywood disc is initially held in place with duct tape until it can be firmly anchored with steel tube stock or metal bars to prevent it from being displaced by the expanding urethane foam.

The plywood disc is initially secured to the bottom of the cryostat with duct tape and then clamped firmly into place using rigid steel tube stock or metal bars and heavy-duty C-clamps, as shown in Figures 6.2 and 6.6

The  space between the plywood disc and the bottom of the cryostat can now be filled with supporting, rigid, closed-cell urethane foam. The foam used for this is MF-1002 1.2 lb density urethane foam (from Michigan Fiberglass Sales). The foam is prepared from a two component kit consisting of  urethane resin (part-A) and activator (Part-B) which are mixed in equal parts using a wooden paint mixing-type stick in disposable 2-gallon paper pails. The resin, activator, paper pails and wooden mixing paddle are included with each MF-1002  kit.

Figure 6.3: The two (A&B) components of the urethane foam are mixed in disposable paper pails using a wooden mixing paddle (also disposable). The foaming reaction begins almost immediately and is well underway within a minute.

Figure 6.4: Foaming action of the combined resin and activator less than a minute after being combined and thoroughly mixed in the mixing-dispensing pail.

Once the components are mixed, the activated urethane resin will expand to ten times its starting volume and will subsequently harden into dense foam. The foaming action begins within 60 seconds of the start of mixing of the resin and activator, so it is necessary to quickly pour the mixture into the holes in the plywood. The activated urethane resin is poured into the headspace using disposable funnels made from lightweight aluminum sheet metal (~22 gauge). The resulting urethane foam requires approximately an hour to set and  is fully cured in 24 hours.

Figure 6.5: Lightweight flexible aluminum sheet metal is formed into half-cones which are taped in place to form funnels. These disposable funnels are then used to facilitate pouring the mixture into the 5″ holes cut into the plywood discs, starting with the lower holes and finishing up with the top holes.


Figure 6.6:Once the urethane foam has filled the headspace and has stopped exhausting from the filling holes, the holes are covered with squares of plywood which are screwed into place. The plywood disc should then be primed and painted with a waterproof oil-based, or two-part epoxy concrete floor paint, to prevent subsequent water damage due to efflorescence from the concrete slab, or insect (termite) infestation.

Four to six 2-gallon pails of the activated resin mixture is typically enough for each cryostat. [ The density of the foam may be altered by changing the ratio of resin and activator: more part-B than part-A results in a larger final volume of foam with less density.]

The cryostat is now ready for movement to the patient storage area of the facility for erection to a vertical position, fire-retardant coating, final hardware outfitting, painting and placement into service.
