HPLC COLUMN OVEN– HS - 100
This is for regular use where the need is to control the temperature at least 10ºC to 15º C above ambient. It uses heaters and PID controller to give the desire accuracy.

HPLC COLUMN OVEN–CHS - 5 FOR SUB AMBIENT TEMPERATURES

Model CH-S, HPLC Column Oven is based on Peltier effect. Conventional HPLC column ovens utilise heater for generation of heat as such they are useful for above ambient temperatures. All such commercially available column ovens .have limitations in controlling the temperature near ambient. Their temperature range is specified as 10° to 15° C above ambient to - etc.

That is why they are not suitable for temperatures around 30° to 35°C. (Near ambient)

TSI Column oven Model CH-S works on the principle of peltier effect. The solid state peltier element can function either as a cooling device or as a heater. The temperature can be even controlled to sub ambient temperature. The range of CH-5 is 5° to 90°C.

It uses microprocessors based, com pat PID controller & can help to achieve stability of +0.2°C
