7. Operating procedures
7.1. Bath fluids
Caution:
No liability for use of other bath liquids!
Please contact JULABO before using other than recommended bath fluids. JULABO
takes no responsibility for damages caused by the selection of an unsuitable bath fluid
Do not use alcohols.
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.
No liablity for use with water. Danger of freezing at working temperatures <5 °C.
Recommended bath fluids:
Bath fluids Temperature range
soft/decalcified water 5 °C to 80 °C

 The power supply plug serves as safe disconnecting device from the line and must
be always easily accessible.
