Dow Corning DC 704 Silicone Pump Fluid

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.
