Description

Application

Silicone oil has been used:

• for melting-point and boiling-point apparatus
• in membrane contactors to impregnate fibers
• on rheometer samples (chicken skin and bovine gelatin) to prevent evaporation during heating using temperature sweeps and frequency sweeps

Biochem/physiol Actions

Silicone oil is suitable for use in under-oil screenings of proteins.
