TMC-19 VACUUM PUMP FLUID

TMC-19 Vacuum Pump Fluid is a molecularly distilled, hydrotreated paraffinic oil for use in mechanical vacuum pumps.  TMC-19 will support vapor pressures down to 1x10-5 Torr.  If deeper vacuum is desired, TMC-20 would be a viable option.   APPLICATIONS Mass Spectrometry Electron Microscopy Thin Film Sputtering UHV Systems Freeze Dry Systems Non-Corrosive General Applications ** Not recommended for oxygen and highly reactive gas loads.**   PHYSICAL PROPERTIES Property Result Vapor Pressure @ 25 °C 1X10-5 Torr Viscosity @ 40 °C 59 cst Pour Point -18°C Specific Gravity @ 22 °C 0.86 g/ml Flash Point - C.O.C. 235°C - 455°F Fire Point - C.O.C. 260°C - 500°F   PERFORMANCE An independent testing laboratory performed a modified RBOT D-2272 test to determine the oxidative stability of TMC-19 compared to Inland 19.  This test employs a method to achieve rapid oxidation of the lubricant tested and then measure the degradation characteristics of the
