SV-D3 Diffusion pump oil

 Diffusion pump oil has narrower range of distillate scope, has favorable capability of heat stability and oxidation stability, the lower of saturated vapor pressure, can get terminal vacuum of 10-8Kpa.

Implementation of standards: SY1635-66

Oil Selection:

All working fluid must not mix, the same types of different brands of liquid, because the boiling point are different, so there can not be mixed up.
Instruction:
1. Must use of under the best the heating power.

2. Must clean out survivals liquid completely when changing the oil                                                                                                                                                                                
3. Oil product should be stored where is shade, dryness and low temperature. Strictly prohibit to be mixed with moisture, dust, impurity and so on.
