Julabo Thermal C20S Overview
Julabo Thermal C20S is a light brown, 20 cSt stabilized silicone heat transfer fluid for open-bath heating from 0 to +220 °C. An added stabilizer delays oxidation, extending service life during sustained high-temperature operation. Labs choose C20S for hot oil-bath work that ordinary fluids cannot endure for long.
Silicone chemistry stays inert against common metals and holds very low electrical conductivity. Operators should avoid silicone tubing, which silicone fluids degrade. Above 150 °C the fluid forms vapor below the flash point; ensure adequate ventilation at elevated temperatures. Regular fluid checks near +220 °C keep performance consistent.

Laboratory Applications
Thermal C20S serves high-temperature heating baths in chemistry, materials, and QC labs operating to +220 °C. The stabilizer suits sustained hot runs such as dissolution, elevated viscometry, and oil-bath sample work. Its light brown color is normal for the stabilized formulation.
Pair C20S with a heating circulator rated for the same upper range. Schedule fluid checks every few months when running near +220 °C to track oxidation. Confirm the fluid matches your unit before filling.

Product Documentation
Frequently Asked Questions
What is the temperature range of Thermal C20S?
Thermal C20S operates from 0 to +220 °C in open-bath heating circulators, with a 20 cSt viscosity.
Why is Thermal C20S brown, and what does the stabilizer do?
The light brown color comes from an added oxidation stabilizer. That stabilizer slows breakdown at high temperature, extending the fluid's service life.
How often should the fluid be checked?
When running near +220 °C, check or replace the fluid every two to three months. Vapor near the upper limit is normal and stays below the flash point.
