Product Introduction:

The chromatographic column constant temperature box is an important supporting equipment for chromatographic instruments. Correctly controlling the temperature of the chromatographic column, improving the column efficiency and sensitivity, enhancing the separation of chromatographic peaks, shortening retention time, and reducing back pressure are essential for achieving ideal analytical results. The AT series chromatographic constant temperature column box adopts advanced "AI" artificial intelligence algorithm and has self-tuning (AT) function. The high brightness digital display shows the set temperature (SV) and actual temperature (PV) respectively, with high temperature control accuracy and easy operation. It also comes with ultra-high temperature automatic power-off function.

Product features:

The horizontal integrated design facilitates the placement of column boxes and their compatibility with HPLC systems.

2. The spacious constant temperature chamber can not only accommodate three chromatography columns with a diameter of 4.6mm and a length of 300mm, but also place the injection valve (or switching valve) at a constant temperature inside the chamber, which will greatly improve the constant temperature effect on the mobile phase entering the chromatography column.

3. Three independent constant temperature chambers and preheating/cooling capillary tubes can further improve the constant temperature effect of the mobile phase.

4. Adopt advanced "AI" artificial intelligence algorithms and prepare self-tuning (AT) functions.

5. Double four digit display of set temperature (SV) and actual temperature (PV), with automatic power-off function for overheating.

The drainage channel designed at the bottom of the column box constant temperature chamber can discharge the water vapor condensate generated on the surface during column leakage or constant temperature chamber cooling.
