Low-viscosity PCTFE fluid for cryogenic calibration and heat transfer. Optimized for cryogenic calibration baths around -100°C, it is a drop-in replacement fluid for the Fluke 7380, 7381 and 7081 and Kaye CTR-80 cryogenic bath systems. Nonflammable and inert — also used in refrigeration, freeze-drying and coal Float-Sink testing. Korea stock available.

Its low viscosity (0.8 cSt) gives excellent flow even at cryogenic temperatures (pour point -129°C), and being nonflammable and inert it is safe for precision calibration and test environments.
Halocarbon PCTFE oils are graded by viscosity (cSt). Select the viscosity that matches your process conditions.
