Nalgene™ vacuum chamber systems include a transparent jar and gasketed vacuum plate with a tubing adapter that fits 1/4" I.D. tubing. They withstand full vacuum without risk of implosion or shattering and are useful as a controlled environment chamber for degassing operations and freeze drying. The one gallon size is a polycarbonate jar with a white polypropylene plate intended for applications using nonaggressive chemicals such as student demonstrations of vacuum procedures. The two larger are amber polyetherimide jars with a white polycarbonate plate. Polyetherimide offers excellent chemical resistance to acids, bases, aliphatic alcohols and hydrocarbons, and saturated halogenated hydrocarbons.
WARNING: Do not autoclave vacuum jars when used for vacuum service. Do not use with unsaturated halogenated hydrocarbons.
