External column heater

Column Heater is an essential part to HPLC/IC. To achieve the desired analysis effect, correctly manages column’s temperature,improves the column’s efficiency, sensitivity, improves distances among chromatogram peaks, saves time, lowers reverse pressure- all are essential elements to a high quality operation.

Technology advantage:

  • lflexible placement:two-in-one placement design -- vertical and horizontal

  • laccurate temperature controlling and display:4-digits LED temperature set and display makes the temperature controlling accuracy to  +0.1℃。

  • lquick installation:magnetic heating chamber and its lid

  • lconvenient observation :the glass window on the heating chamber can make you observe the working status of heating column easily

  • lsafe anti-leaking design:when in vertical placement, leakage box under the heating chamber prevents further leakage

  • lflexible fixation :stainless-steel spring column bracket in heating chamber, one or two columns can be placed when replace the bracket

  • lunhindered tubing channels:the tube’s inlet and outlet of the heating chamber is with smooth transition to ensure it passes through easily

  • lstable column under pan:when needed, connect the attached wide under pan with the column heater to increase the stability in vertical placement
