Hi-temp calibration bath fluid

This high temperature fluid offers industry a non-toxic, versatile bath fluid that has proven to be cost effective and thermally stable at temperatures up to +315°C. This fluid has demonstrated excellent performance over a wide range of temperature without compromising economics or system integrity. Unlike the less stable mineral oil based fluid, our high temperature fluid provides the user with the confidence and reliability without the premium price of other fluids. Recommended temperature range +60 to +250°C.

Benefits and features
- Low viscosity
- Improves bath uniformity and stability
- Enhanced heat-up and cool down rates
- Lower cost than glycol and silicone oil fluids
- Safe and non-toxic
- Convenient 18L (5 gallon) container

- Not for long term (more than a few hours) continuous use above 100°C because excessive oxidation will occur.
- As with most high temperature fluids, a fume hood is recommended for operating temperatures above 150°C.
- Should only be used with the following plastics; ABS, Epoxy, Acetal, PTFE, Viton, Kalrez, Chemraz, Fiberglass, Graphites, Fluroelastimers.
- For other plastic types contact Techne for specific recommendations.

Ordering Information

Product Code Description
FHTFHI High Temperature Bath Fluid 18 litre container

There is no absolute number of times Techne oils can be heated and cooled but 2 things must be considered.
1. If the bath cycles fluid between ambient and maximum recommended temperature, then over time the fluid may degrade. The amount of time this takes can vary from bath to bath. So if the user identifies changes in colour, viscosity and temperature efficiency to the fluid this indicates the fluid is ready to be changed.
2. If the fluid is being cooled to sub-zero temperatures, moisture from the atmosphere can condense into the fluid and crystalize when the fluid is being cooled down. The customer will see the fluid turn a slightly milky white color due to ice crystals forming.
