About This Product
Because the pump is part of the base, the jar can be evacuated quickly on the bench without a separate vacuum pump, ready for vacuum physics experiments or any work that needs an evacuated space. The gauge shows the vacuum reached, and the release valve lets air back in when the work is finished. Educational Lab Equipments can supply and export the Bell Jar to Moldova, Malta, Kiribati, Rwanda, Brazil and Gambia.
Frequently Asked Questions
Does the Bell Jar need a separate vacuum pump?
No. A manual exhaustion piston pump in the base evacuates the jar, making it a complete self-contained apparatus.
Can the bell jar be autoclaved or used with solvents?
No. It is non-autoclavable, and exposure to organic solvents or vapours, or to other aggressive chemicals, should be totally avoided.
How is the jar sealed to the base?
A rubber gasket ring on the pump base gives an airtight seal with the jar.
