Important operating note
Maintain the correct liquid level, avoid electrical contact with spills and use suitable racks or containers. Operating liquid and temperature must match the method. Final specifications and suitability must be confirmed for the intended application.
Request specifications and a quotation for the Low Temperature Water Bath.
Planning a low temperature water bath enquiry
Refrigeration removes heat from the bath while the controls maintain the intended liquid condition. The bath fluid must remain suitable throughout the chosen range. The name water bath should not be read as permission to use plain water at every low-temperature setpoint.
Match the configuration to the procedure
Below-ambient testing requires the quoted refrigeration option to meet the target temperature. Specify the working liquid and load, and confirm the selected lower endpoint and operating conditions.
What should be checked before using a sub-ambient bath?
Confirm the permitted bath fluid, useful operating range, sample load and pull-down requirements. Ask whether the quoted performance applies to the proposed fluid and loading arrangement.
Plan care before installation
Keep refrigeration ventilation unobstructed and follow the manual for liquid changes and cleaning. Inspect for condensation or spills around electrical parts and use the prescribed shutdown procedure.
Review the Low Temperature Water Bath specifications and available configurations before preparing a purchase request. Keep the required performance separate from any optional items, and ask for each included accessory to be identified in the quotation.
