5.2. Bath fluids
Caution:
No liability for use of other bath fluids!
Do not use flammable bath fluids!
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.
• Danger of freezing at working temperatures <5 °C.
Glycol: - Low toxicity - Strictly observe the safety data and handling
instructions from the manufacturer.
Water/glycol mixture:
Water evaporates and thus the mixture may become flammable. In the
heating phase, a fire may be caused due to the hot surface temperature
of the heater.
Fill up water in time and check the mixing ratio in regular intervals (e.g.
using an appropriate device).
• Recommended bath fluid:
Notice:
Please contact JULABO before using other than recommended bath
fluids. Only use non-acid and non corroding bath fluids.
JULABO takes no responsibility for damages caused by the selection of
an unsuitable bath fluid.
Unsuitable bath fluids are liquids which e.g.
• are very highly viscous
(much higher than 30 mm
2
/s at the respective working temperature)
• have corrosive characteristics or
• tend to cracking.
