Selecting a Circulating Bath<br />
The best PolyScience Circulating Bath for your application will depend on a number of factors.<br />
Here are some guidelines to help with your selection:<br />
1. Working <strong>Temperature</strong> and Stability – You will need<br />
a Refrigerated/Heated Circulator if your working<br />
temperature will ever be near or below ambient.<br />
Applications that require maximum temperatures<br />
above 160°C or ±0.01°C temperature stability require<br />
Circulators with Performance or Advanced Series<br />
<strong>Temperature</strong> <strong>Control</strong>lers.<br />
2. Cooling/Heating Demand – A Circulator with a<br />
small reservoir is generally suitable if you require<br />
external circulation only and the heating/cooling<br />

Heating Rates Cooling Rates<br />
demand is moderate. If the external heating/cooling<br />
demand is high or you will be putting samples in the<br />
internal reservoir, a Circulator with a larger reservoir<br />
will be required.<br />
3. External Circulation – All PolyScience <strong>Temperature</strong><br />
<strong>Control</strong>lers can be used for close-loop external<br />
circulation. If open-loop external circulation is required<br />
or if your application requires a flow rate above 3 gpm<br />
(11 l/min), a Circulator with a Performance or Advanced<br />
Series <strong>Control</strong>ler is required.<br />
