Approved Fluids

Only use the approved fluids listed in this manual.
Thermo Fisher Scientific takes no responsibility for damages caused by the selection of an
unapproved fluid.
Ensure, when selecting the heat transfer fluid, that no toxic gases are generated.
Inflammable gases can build up over the fluid during usage. Other than water,
handle and dispose of approved fluids in accordance with the fluid manufacturer's
specification and/or the fluid's Safety Data Sheet (SDS).
To set the fluid temperature alarms, use the bath's menu selection to identify the fluid,
see Chapter 4.
When using water above 80°C closely monitor the fluid level, frequent top-offs will be
required. It will also create steam.
Glycol/Water mixtures require top-offs with pure water, otherwise the percentage of
glycol will increase resulting in high viscosity and poor performance.
Ensure the over temperature cut-off point is set lower than the fire point for the heat
transfer fluid selected.
The highest working temperature, as defined by the EN 61010 (IEC 1010), must be
limited to 25°C below the fire point of the fluid.
Refer to Chapter 4 for fluid set point ranges.
Water, Distilled Water or Deionized Water
Normal tap water leads to calcareous deposits necessitating frequent bath decalcification.
Calcium tends to deposit itself on the heating element. The heating capacity is reduced and
service life shortened.
Well or municipal water should not be used unless it has been tested by a lab to meet the
minimum requirements shown on the next page. The primary risks of using untested and
untreated tap water are corrosion caused by an out of range pH value and/or the concentration of
dissolved solids, and those dissolved solids precipitating out of solution and forming scale.
