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-950 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:

1. The use of "Peltier" (semiconductor heating and cooling module) element heating/cooling technology can make the structural design compact and the control accuracy high.

2. The integrated design makes the column temperature box easy to place and compatible with the HPLC system, with a compact structure.

3. A temperature control better than ± 0.3 ℃ makes the experiment more precise.

4. The intelligent temperature control system can automatically select heating or cooling based on the difference between the ambient temperature and the set temperature, making it extremely convenient to operate.

5. The AT-950 chromatographic constant temperature chamber adopts advanced "AI" artificial intelligence algorithms and has self-tuning (AT) function.

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

7. The spacious constant temperature chamber can accommodate three chromatography columns with a diameter of 4.6mm and a length of 300mm.

8. The cooling function of the column box makes its applicability more extensive, and the powerful cooling power can lower the temperature inside the temperature chamber to 25 ℃ below room temperature.

9. Equipped with a capillary preheating tank.

10. Randomly equipped with a height adjustable injection valve mounting bracket, and complimentary overflow bottle, bottle holder, and aluminum alloy thermal block. Aluminum alloy thermal block can accelerate the thermal conductivity speed.

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.
