Selecting Circulating Water Baths

The Best Polyscience circulating water bath for your application will depend on a number of factors. Some Guidelines to help with your selection:

1. Working Temperature and Stability

You will need a Refrigerated/Heated Circulator if your working temperature will ever be near or below ambient. Applications that require maximum temperatures above 160C or +/- 0.01C temperature stability require Circulators with Performance or Advanced Series Temperature Controllers.

2. Cooling / Heating Demand

A circulating water bath with a small reservoir is generally suitable if you require external circulation only and the heating/cooling demand is moderate. If the external heating/cooling demand is high or you will be putting samples in the internal reservoir, a Circulator with a larger reservoir will be required.

3. External Calibration

All Polyscience Temperature Controllers can be used for close-loop external circulation. If open-loop external circulation is required or if your application requires a flow rate above 1L/min, a circulator with a Performance or Advanced Series Controller is required.
