Advanced Digital Refrigerated Circulator  Maintains Electrophoresis Temperatures with ±0.01°C Stability
A high-performance circulator that provides the precise cooling needed to enhance electrophoresis separations is available from PolyScience. Compact and easy-to-use, the Advanced Digital Refrigerating Circulator combines intuitive touch-pad operation with automatic or user-adjustable fluid optimization and ±0.01°C temperature stability to maintain buffer solutions at optimum temperatures even under varying electrophoresis voltages. 
The Model AD07R-20 features a -20° to +200°C working temperature range, large 3.75” LCD display, and variable speed pressure-suction pump. This versatile circulator also incorporates a wide variety of lab- and operator-friendly features, including a rotating control head that provides a clear view of the temperature display anywhere within a 180° viewing radius, self-storing reservoir cover, and a molded composite top plate that dampens noise and remains cooler at high temperatures. Other standard features include remote temperature sensing capability as well as serial and USB connectivity. The AD07R-20 has a 7 liter reservoir; other models, with reservoir sizes as large as 45 liters, are also available.
