Product Description

The Bel-Art 420430000 vacuum chamber for lab use has a polycarbonate jar with an internal volume of .21 cubic feet, an acrylonitrile butadiene styrene (ABS) plastic plate, and a polypropylene valve with plug. The jar is clear polycarbonate for shatter resistance and easy viewing of contents. The plate is strong and lightweight. The polypropylene valve accepts 1/4-inch (6.4 mm) interior diameter tubing, and has a Teflon plug to help control airflow and gently release the vacuum. The plate seals to the jar with an O-ring (included). Three rubber bumpers attach to the plate to help reduce slippage.

The jar has an internal volume of .21 cubic feet. The jar is 4-3/8 inches/11 cm high and has an interior diameter of 7-7/8 inches/20 cm. The plate is 1-3/4 inches/44 mm high and has a diameter of 9-1/8 inches/232 mm. The valve can be used with 1/4-inch (6.4 mm) interior diameter tubing. The chamber weighs approximately 2.5 lb.

Vacuum chambers, sometimes called desiccators, are rigid containers from which air and other gases can be removed by a vacuum pump. The resulting vacuum environment allows researchers to conduct experiments and test mechanical devices. They are commonly used in laboratories for experiments, drying, degassing, and demonstrations.

Bel-Art Products manufactures scientific products, including lab ware, testing equipment, and safety supplies. The company, founded in 1946 and headquartered in Pequannock, NJ, also makes products under the Scienceware brand.
