Edwards 45 oil

Edwards supplies the widest range of oils of different viscosities and specifications to enable customers to obtain the best performance from mechanical pumps under different application conditions. All are specially prepared for high vacuum use, having low vapour pressures even at high temperatures. The particular mechanical pump specification should be consulted to find which oil to use.


Features and Benefits

  • Edwards 45 is a hydrocarbon synthetic polymer whose molecular structure offers chemical inertness, high temperature stability and low vapour pressure (<10-7 mbar at 25 °C). Edwards 45 oil is non-toxic, non-corrosive and reclaimable.

It is commonly used in mass spectrometry applications because of its well defined peaks.
