BELL JAR WITH VACUUM PUMP HAND OPERATED (0073)
A complete self-contained apparatus suitable for vacuum physics experiments and applications requiring evacuated space. Transparent jar and pump, both having unbreakable ABS body. Jar provides a robust chamber capable of withstanding full vacuum without danger of implosion or shattering and fitted with a vacuum gauge and vacuum release valve. A rubber gasket ring on the pump base ensures airtight seal with the jar. A manual exhaustion piston pump in the base provides quick and convenient evacuation of the jar. Note: The exposure or contact of the apparatus to organic solvents or vapours, or to other aggressive chemicals is to be totally avoided. The apparatus is non-autoclavable
