Chemical structure:

Vaccum Diffusion Pump Oil IOTA702 is a kind of general purpose oil designed for fast pumping of large volumes of gas. It is used to produce vacuums in the range of 10-5 to 10-7 torr. It possesses excellent heat stability, good resistance to oxidation and radiation. Its vapour pressure is very low under room temperature, and changes sharply with the variation of temperature
