5.2. Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid used, particularly with regard to
the fire point!
If a bath fluid with a fire point of
65 °C is used, only supervised operation is possible.
Water: The quality of water depends on local conditions.
 Due to the high concentration of lime, hard water is not suitable for temperature
control because it leads to calcification in the bath.
 Ferrous water can cause corrosion - even on stainless steel.
 Chloric water can cause pitting corrosion.
 Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.
Recommended bath fluids:
Bath fluid Temperature range
soft/decalcified water 5 °C to 80 °C
mixture water/glycol, mixture 1:1
-20°C to 50°C

Caution:
Fire or other dangers when using bath fluids that are not recommended:
Use only nonacidic and noncorrosive bath fluids.
JULABO assumes no liability for damage caused by the selection of an unsuitable
bath liquid.
Unsuitable bath fluids are fluids which, e.g.,
 are highly viscous
(much higher than recommended at the respective working temperature)
 have a low viscosity and have creep characteristics
 have corrosive characteristics or
 tend to crack.
 No liability for use of other bath fluids!
