The vacuum chamber models are used in ESD-protected zones and prevent the build-up of electrostatic charges. The structure is made of stainless steel, the lid is made of aluminum, and the wheels are conductive. The use of an oil-lubricated vacuum pump allows a high vacuum to be achieved. The end of the evacuation process can be programmed; there is a control sensor in the chamber. - An oil-sealed vacuum pump allows a high vacuum to be achieved - Version: without inert gas
