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:

Caution:
Fire or other dangers when using bath fluids that are not recommended:
Please contact JULABO before using other than recommended bath fluids.
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!
