PolyScience 9100 Series 6 Liter Refrigerating/Heating Circulators

This series features a 6 liter reservoir in a space saving vertical design. Only 8¼” (21cm) wide, their small foot print conserves precious bench space.
Size configuration plus a choice of four controllers with excellent performance make this series our most popular circulators.

Dependable, precise and compact, all models feature redundant over temperature and low liquid level protection.

The refrigeration system is designed to be used below 70°C. This allows rapid bath cooling from 70°C or lower, plus maximizes temperature control and reduces energy consumption above 70°C. The hermetically sealed compressor is designed for years of maintenance-free use.

Analog Model 912
Ideal for routine applications where extreme accuracy and stability are not critical. An excellent alternative to tap water cooling for rotary evaporators and condensers at a low price. Convenient set-point dial with supplied thermometer (alcohol) readout.

Standard Model 9106
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.

Digital Model 9102
The digital controller has all the advanced performance as the programmable model and is your ideal choice when remote probe, time/temperature programming and communication software are not required. The LCD display also incorporates multi-language help menus that aid in setting up operation while using the Select/Set knob. A built-in RS-232 interface is standard. The 5-speed pressure/suction pump can be used in both open and closed loop applications. Great performance for those on a budget.

Programmable Model 9112
This top-of-the-line model features a wide temperature range and time/temperature programmability. Programs can be set directly from the front panel with the aid of the Select/Set knob and multi-language display, or from a PC using the RS-232 interface. LabView™ drivers and Excel® macros offer even greater programming and data logging convenience. Remote probe capability plus 5-speed pressure/ suction (duplex) pump further enhance the 9112's capabilities.
