Bell jar w/hand vacuum pump

Specifications

Apparatus consisting of a transparent bell and a manual vacuum pump, both made of resistant ABS plastic for carrying out vacuum physics experiments.
The bell provides a robust chamber capable of withstanding full vacuum without danger of implosion or rupture and equipped with a pressure gauge and vacuum release valve.
A rubber gasket at the base ensures the perfect sealing of the hood.
The manually operated pump located at the base provides a quick and efficient evacuation of the air in the hood.
Gauge units: mmQS (equivalent to mmHg).
Pressure gauge scale: 0 to -600 mmQS, with red safety line at -250 mmQS (-33 kPa).
