Cast Acrylic Properties
Better known by name brands such as Plexiglass, Acrylite, Chemcast, Methacrylates, etc. Acrylic plastic offers durability and is an excellent substitute for glass, acetate, polycarbonate or PVC when one is looking for transparency or translucency. It is half the weight of glass and 45% the weight of aluminum. Maximum Service Temperature, Air 65 - 112 °C 149 - 234 °F Average = 94.5°C; Transmission, Visible 92%.

Altitude vs. Pressure, Temperature and Density
This table gives density in slugs per cubic foot because it uses the American system of altitude in feet, pressure in inches of mercury and temperature in degrees Fahrenheit. While people often use pounds per cubic foot as a measure of density in the U.S., pounds are really a measure of force, not mass. Slugs are the correct measure of mass. You can multiply slugs by 32.2 for a rough value in pounds.

Highest Quality Materials, Most Cost-Effective Design and Fabrication
Simple or Complex
We can build your vacuum chamber (large or small) into a complete vacuum work station with a heavy duty cart and swivel casters allowing the whole system, chamber, controller, plumbing and pump, to be portable and compact enough to be easily moved and used anywhere or stored when not in use. Depending on your materials and application, various pumps, traps, filters, valves and fittings are available. Abbess can suggest or the customer can select the type and make of pump to be included, if needed.
Abbess uses the highest quality materials and components available. The non-corrosive/non-rusting construction and true O-ring seals ensure many years of use, even in the toughest of conditions. Abbess Instruments' Vacuum Chambers are dependable and reliable in everyday use. They are currently in use around the world, in many different Industries, Government Labs, Corporate R&D, Colleges and Universities.

Founded in 1982, Abbess provides instruments and systems for science and industry. It has provided custom instruments and systems applications for national labs, corporate research labs, and supported research projects to more than 100 universities. Among the products available from Abbess are cryostats and cryogenic systems, Hall Effect and Resistivity measurement systems, wide temperature range cryogenic workstations, gas and liquid control and delivery systems and Vacuum Chambers, supplied domestically and around the globe. Abbess also provides vacuum chambers that integrate heat and cryogenic features for deep temperature cycling. Abbess products are used in a wide variety of applications including deep space simulator chambers, degassing epoxy for molding and drying herbs. Abbess developed cryostats used to support the National Ignition Facility (NIF) effort. Abbess has the flexibility to deliver both standard and custom equipment to meet exacting specifications. The company's design, engineering and manufacturing capacity covers vacuum systems, cryostats, cryogenics, magnetics, thermal dynamics, materials and heat transfer, software, algorithms and mathematics. Since its founding, over twenty years ago, Abbess Instruments has designed and delivered to military and government laboratories, universities and top industry research and development laboratories.
Abbess' flexibility provides customers with many options. Rather than being limited to a few catalog items, Abbess customers have the freedom to order either a previously designed instrument as shown here, or to have new instrument designed to the exact specifications they need.
