Julabo Thermal C50S Overview
Julabo Thermal C50S is a light brown, 50 cSt stabilized silicone heat transfer fluid for open-bath heating from +20 to +250 °C. 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.
An 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.

Laboratory Applications
Thermal C50S serves high-temperature heating baths in chemistry, materials, and industrial labs running to +250 °C. The viscous, stabilized formulation suits prolonged hot work such as high-temperature dissolution and oil-bath conditioning. Darkening over long high-heat runs is normal and does not signal failure.
Pair C50S with a heating circulator rated to the same upper limit. Monitor fluid health near +250 °C and change it on schedule to prevent thickening or polymerization. Provide ventilation whenever the bath runs above 150 °C.

Product Documentation
Frequently Asked Questions
What is the temperature range of Thermal C50S?
Thermal C50S operates from +20 to +250 °C in open-bath heating circulators, with a 50 cSt viscosity.
Is it normal for the fluid to smoke and darken at high temperature?
Yes. Above 150 °C silicone fluids produce normal smoke and vapor below the flash point, and the stabilized fluid darkens over extended high-heat use. Ensure ventilation and monitor fluid health.
How should the fluid be maintained?
Check fluid health regularly near the upper limit and change it on schedule to prevent thickening or polymerization. Consult the SDS for handling and disposal.
