Machined Vacuum Pump Plate, 175mm Diameter

This machined pump plate is constructed from aluminum and features an integrated tube for pump connection and a stopcock for air regulation. The plate is mounted on a painted heavy tripod base for stability and comes supplied with a rubber seal to facilitate airtight sealing in bell jar experiments. The plate has a diameter of 175mm. The central pillar design allows connection to a vacuum pump while the stopcock provides precise control over air flow during demonstrations of atmospheric pressure, vacuum principles, and related physics experiments.
