Product Overview

Silicone Oil (Lab) (CAS No. 63148-62-9) is a laboratory silicone fluid based on polydimethylsiloxane-type polymeric material. The siloxane backbone provides chemical and thermal characteristics distinct from hydrocarbon oils, while the methyl-substituted polymer structure gives the fluid low chemical reactivity toward many routine laboratory materials and useful heat-transfer behaviour. Because CAS No. 63148-62-9 covers polymeric silicone-fluid material rather than one discrete molecular species, no molecular-weight distribution or viscosity is inferred.

This laboratory product is specifically designated for use in oil baths up to 250°C in accordance with the submitted product instruction. Its role is to provide a fluid heat-transfer medium for controlled laboratory heating rather than to function as a synthetic reagent.

Typical Applications

• Laboratory oil baths for controlled heating up to the submitted 250°C service limit.
• Heat-transfer medium for reaction vessels and laboratory glassware.
• Temperature-controlled heating during synthesis and analytical sample preparation.
• Laboratory calibration and thermal-equilibration setups compatible with silicone oil.
• Heating baths requiring a non-aqueous fluid medium.
• General thermal-control experiments within the specified product-use range.

Common Synonyms

• Polydimethylsiloxane
• Dimethylpolysiloxane
• PDMS
• Silicone fluid
• Silicone oil

Storage Conditions

Keep tightly closed and protect from dust, water and chemical contamination that could alter fluid cleanliness or heat-transfer behaviour. Avoid mixing with other bath fluids or degraded residues where reproducible laboratory heating performance is required.
