High Vacuum Pump Oil Designed specifically for use with Fischer Technical  Company High Vacuum Pumps.  This non-detergent high vacuum pump oil is hydro processed to attain its stable, viscous and refined properties.  This process also results in a clear mineral oil that will alert of contamination sooner if the oil becomes milky or cloudy. High Vacuum Grease This vacuum grease helps provide a proper seal between the vacuum pump plate and the bell jar so that high vacuum pressures can be achieved. "The Tank" Oil Change System All vacuum pumps require changing oil after every use. Contaminated oil, laden with moisture and acid will damage pumps and shorten pump life. On top of that, deep vacuums cannot be achieved with contaminated oil. Maintaining clean oil in your pump will ensure that your pump will operate at peak efficiency. No More Mess & Spills Environmentally Friendly!  The Tank is Easy to Use: Turn black cap counterclockwise to open. Place vacuum pump in the cradle and drain pump. Once the pump has finished draining, turn the black cap clockwise to close after every use. Holds up to 5 oil changes. Vacuum Gauge and Fittings Bourdon tube vacuum gauge and fittings to add to your Fischer Technical company LAV series high vacuum pumps. Ships complete with gauge, fittings, and sealant. High Vacuum Pump With Gauge These rotary style, 2 stage direct drive pumps are ideal for use in the laboratory in virually all applications where a vacuum of up to 25 microns is desired.  The pumps use High Vacuum pump oil (one quart included) and are designed to run on a closed system.  The vacuum should not be regulated, but rather these pumps should be used with vacuum ovens, desiccators, etc where a consistent, high vacuum is required.  Regular oil changes and proper maintenance will ensure these pumps will last for years in your laboratory.
