CF41

The Cryo-Compact refrigerated/heating circulators have a very small footprint which is ideal for placing on bench top or in a fume hood with limited space. Models feature M16x1 male pump connections for external temperature applications with 8 and 12 mm hose barbs.
The HighTech CF31/CF41 units have a working temperature range from -30(-40) to +200 °C and include a dual screen display with numeric keypad for easy data entry and instrument reading. RS232 port for external communication and Pt100 sensor connection for external monitoring and control. A 4-speed centrifugal pressure / suction pump provides 22-26 L/min flow with 5.8-10.2 psi pressure / 2.9-5.6 psi suction. Integrated programmer with 6 x 60 program steps.

Included with each unit: 2 each barbed fittings for tubing 8 and 12 mm inner dia. (pump connections M16x1 female).
