The higher viscosity and added stabilizer suit sustained operation at the top of the heating range. Labs choose C50S for demanding hot oil-bath work where lighter fluids degrade quickly.\u003c\/p\u003e\n\u003cp\u003eAn oxidation stabilizer extends service life, though the fluid naturally darkens with extended high-temperature use. Above 150 °C the fluid produces light smoke and vapor, a normal property that stays below the flash point. Ensure adequate ventilation at elevated temperatures and consult the SDS for handling. Avoid silicone tubing, which silicone fluids degrade.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eHeat Transfer Fluid\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFluid Type\u003c\/th\u003e\n\u003ctd\u003eSilicone, stabilized\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eViscosity\u003c\/th\u003e\n\u003ctd\u003e50 cSt\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eLight brown\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eWorking Temperature Range\u003c\/th\u003e\n\u003ctd\u003e+20 to +250 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eCompatible Equipment\u003c\/th\u003e\n\u003ctd\u003eOpen-bath heating circulators\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAdditive\u003c\/th\u003e\n\u003ctd\u003eOxidation stabilizer\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePackaging\u003c\/th\u003e\n\u003ctd\u003ePoly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAvailable Sizes\u003c\/th\u003e\n\u003ctd\u003e5 L, 10 L\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eJulabo\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eShips From\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eAvailable Sizes and Configurations\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003cth\u003ePack\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e64504\u003c\/td\u003e\n\u003ctd\u003eThermal C50S Stabilized Silicone Fluid, 5 L\u003c\/td\u003e\n\u003ctd\u003e5 L Poly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e64504\u003c\/td\u003e\n\u003ctd\u003eThermal C50S Stabilized Silicone Fluid, 10 L\u003c\/td\u003e\n\u003ctd\u003e10 L Poly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eThermal C50S serves high-temperature heating baths in chemistry, materials, and industrial labs running to +250 °C.
