PolyScience Brand Water Circulators

Water circulators are used in conjunction with Column Jackets for an effective and economical temperature control of HPLC columns and Post Column Derivatization Kits (EPOCODTM).  The excellent heat exchange capability of circulating liquids ensures uniform temperature of the column without “hotspots”.  Water circulators with chilling capabilities can also be used to reduce HPLC column temperature to below ambient as an effective method for improving separations of temperature sensitive and chiral compounds, and interconverting diastereoisomers.

                     812-240:  voltage 240 volts

Description:  Ideal for routine applications where extreme accuracy and stability are not critical. An excellent method for maintaining a raised temperature in column jackets at a low price. Convenient set-point dial with supplied thermometer (alcohol) readout.

Standard (Digital) Heating Water Circulator

Basic (Analog) Heating/Cooling Water Circulator

Standard (Digital) Heating/Cooling Water Circulator

Temperature range:  Ambient +5 to 150°C

Temperature Stability:  ± 0.05°C

Temperature controller and readout:  Digital, LED display

Readout Accuracy:  ± 0.05°C

Pressure Flow Rate: 2 Speed, 9 or 15 L per minute of flow

Reservoir Capacity: 6 Liters

Catalog #:  8006-120:  voltage 120 volts

                     8006-240:  voltage 240 volts

Temperature controller and readout:  Alcohol thermometer (supplied)

Pressure Flow Rate: 2 Speed, 9 or 15 L per minute of flow

Reservoir Capacity: 6 Liters

Catalog #:  912-120:  voltage 120 volts

                     912-240:  voltage 240 volts

Description: Ideal for routine applications where extreme accuracy and stability are not critical. An excellent alternative to tap water cooling for rotary evaporators, condensers at a low price. Convenient set-point dial with supplied thermometer(alcohol) readout.

Temperature range:  -20 to 150°C

Temperature Stability:  ± 0.05°C

Temperature controller and readout:  Digital, LED display

Readout Accuracy:  ± 0.05°C

Pressure Flow Rate: 2 Speed, 9 or 15 L per minute of flow

Reservoir Capacity: 6 Liters

Catalog #:  9106-120:  voltage 120 volts

                     9106-240:  voltage 240 volts

Description: With the same cooling capacity as more expensive models, this model combines high performance with economy. It is equipped with three user-defined temperature preset buttons for rapid set point changes. The bright LED display provides read and set capability, and its stability of ±0.05°C meets all but the most demanding requirements. Frequently used for cooling electrophoresis cells, viscometers and general lab applications.
