Operation

Using Silicone Oil in the
Probe Tube

Appendix 4-C

The following light and heavy silicone oils may be used instead of mineral oil as the repre-
sentative sample in a probe tube:

• Dow Corning #200 light silicone oil

(dimethypolysiloxane, Sigma #DMPS-5X)

Density: 0.97g/ml
Viscosity: 50cs

Volume to use: 1.7 x volume of buffer in individual sample tube, plus one volume of oil
overlay.

• Dow Corning #200 heavy silicone oil

(dimethypolysiloxane, Sigma #DMPS-V)

Density: 0.97g/ml
Viscosity: 5cs

Volume to use: 2.7 x volume of buffer in individual sample tube, plus one volume of oil
overlay.

Note:

Use these oils only in the proportions outlined above. Using them in any other

proportion (for example, 1:1 with sample tube volumes) will lead to inaccurate sample
heating.
