Description

General description

Silicone oil is typically used for oil baths in research labs for reactions that require heating/reflux temperatures in the range of -50°C to +200°C. Oil baths provide more uniform heat in comparison to other heating devices.

Silicone oil is useful for the preparation of oil baths having a temperature in the range of -50°C to +200°C.

Application

Silicone oil has been used for the protection of carbon steel alloy samples in a study. Silicone oil has also been used as a heat reservoir during NMR (Nuclear Magnetic Resonance) analysis.
