Vacuum Diffusion Pump Oil BL-275
Diffusion Pump Oil BL-275 is a colorless to light yellow transparent oily, single-component fluid designed for ultrahigh vacuum applications. The vapor pressure and back streaming rate of BL-275 is so low that the use of traps or refrigeration is unnecessary for some ultra-high and ultra-clean vacuum applications. It has the highest phenyl content of all silicone diffusion pump oils and the best resistance to radiation.
Equivalent Brand: Dow Corning 705, MT-705, and HIVAC-F-5
