Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Product introduction:
High temperature constant temperature circulating tankWidely used in chemical, petroleum, medicine, biology. A thermally controlled and uniform temperature place for experiments, tests and enterprise production in the fields of physical chemistry, metrology, colleges and universities, electronic instruments, scientific research institutions, etc. conducts constant temperature tests or tests on test samples or products produced. The constant temperature bath control system adopts PID automatic control and LED digital display. Its external circulating pump can output constant temperature liquid in the bath to the outside and rub the second constant temperature field outside the vertical bath, expand the scope of use.
