Data Sheet



The CO20 HPLC column heater is compact and easy to use. It is powered by a universal bench-top power supply for use anywhere in the world. The unit has a 14” long silicone rubber heater under the chamber to provide uniform chamber temperatures.

Setting the temperature is easy. Simply touch the UP or DOWN arrows to scroll the target temperature to the desired level. Target and Actual temperatures are displayed continuously on a two-line, backlit alphanumeric display. When the target temperature is reached and settles to within +/- 0.2°C the Stable Temp light will illuminate.

The chamber is covered with a clear polycarbonate cover held by magnets for easy viewing and access to the column. It comes complete with power supply, power cord for the country of use, counter cable, user’s manual and a one year warranty.
