TMC-19 Vacuum Pump Fluid
Guaranteed Safe Checkout
The TMC-19 Vacuum Pump Fluid from TMC Industries, supplied by Econtrol Devices, is a molecularly distilled, hydrotreated paraffinic oil designed for use in mechanical vacuum pumps. It is a replacement for Inland 19 Oil and supports vapor pressures down to 1 × 10⁻⁵ Torr. For applications requiring a deeper vacuum, TMC-20 is identified as a viable option.
Manufactured using a molecular distillation process, TMC-19 Vacuum Pump Fluid is formulated to deliver reliable lubrication and stable vacuum pump performance. The product features double vacuum distillation, excellent lubricating qualities, reduced backstreaming, and excellent vapor pressure characteristics. These properties make it suitable for a range of professional vacuum pump applications while maintaining dependable operating performance.
TMC-19 has also been evaluated in an independent laboratory using a modified RBOT D-2272 test to determine oxidative stability compared to Inland 19. According to the published test results, TMC-19 lasted longer while exhibiting lower viscosity change and lower sediment weight during testing.
Applications
TMC-19 Vacuum Pump Fluid is suitable for the following applications:
- Mass Spectrometry
- Electron Microscopy
- Thin Film Sputtering
- UHV Systems
- Freeze Dry Systems
- Non-Corrosive General Applications
Note: Not recommended for oxygen and highly reactive gas loads.
