Silicone Oil for Oil Baths up to 250°C is a high-temperature, chemically inert silicone-based fluid widely used in laboratory and pharmaceutical applications for controlled heating and temperature maintenance.
🏭⚗️ Production
Silicone oil is synthesized by polymerizing dimethylsiloxane monomers, resulting in linear or cyclic polydimethylsiloxane (PDMS) chains. The oil is then refined and purified to achieve high thermal stability, low volatility, and chemical inertness, making it suitable for laboratory heating baths up to 250°C.
🔬 Properties
Silicone oil is a clear, colorless, and odorless liquid with excellent thermal stability, remaining stable at temperatures up to 250°C. It is chemically inert, non-flammable, and has low viscosity, allowing uniform heat transfer in oil baths. The oil is immiscible with water and most polar solvents, resistant to oxidation, and exhibits negligible vapor pressure under typical laboratory conditions.
🧪 Applications
In pharmaceutical and laboratory settings, silicone oil is used as a heat transfer medium in oil baths for reactions, distillations, and incubations requiring precise temperature control. It is suitable for use in thermal incubators, water bath substitutes, and heating mantles. Silicone oil also serves in the preparation of high-temperature experiments where chemical inertness is essential to avoid contamination or reaction with experimental materials.
⚠️ Safety
Silicone oil is generally considered non-toxic and safe for laboratory use. However, contact with hot oil can cause severe burns, and inhalation of vapors at high temperatures should be avoided. It should be handled with heat-resistant gloves and safety equipment, and stored in sealed containers away from direct heat sources and oxidizing agents. Spills should be cleaned promptly to prevent slips or fire hazards.
