Tetramethyl tetraphenyl trisiloxane—an ideal fluid for aggressive applications.
Features
Used in medium and large pumping speed diffusion pumps in a wide variety of research and production applications, as lower attainable pressure justifies the additional expense of this excellent fluid
High resistance to oxidation and hydrolysis at operating temperature
Ideal fluid for aggressive applications requiring ultimate pressures (without trapping) in the 10-7 Torr range
With first class LN2 traps, chamber pressures can approach 10-11 Torr range
Applications include vacuum metal casting, diffusion bonding, and instruments (electron microscopes, TOF mass spectrometers, etc.)
NOTE: Do not use silicone fluids in mechanical pumps.
