5.4. Bath fluids
Caution:
Carefully read the material 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 scale in the bath
 Ferrous water can cause corrosion, even on stainless steel.
 Chlorinated water can cause pitting corrosion.
 Distilled water and deionized water are unsuitable. Their special properties
cause corrosion in the bath, even on stainless steel.
Recommended bath fluids:
Bath fluid Temperature range
soft/decalcified water 5 °C to 80 °C
See website for list of recommended bath fluids.
Contact: see page 6
Caution:
Fire or other dangers when using bath fluids that are not recommended:
Please contact JULABO before using other than recommended bath liquids.
JULABO assumes no liability for damage caused by the selection of an unsuitable
bath fluid.
Unsuitable bath fluids are fluids which, e.g.,
 are highly viscous
(much higher than 70 mm 2 x s -1 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!
ATTENTION: The maximum permissible viscosity is 70 mm 2 /s
