Product Details

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.

HC-400 low temperature coolant circulator

Features: The low-temperature coolant circulator adopts air-cooled fully enclosed compressor unit for refrigeration, microcomputer intelligent control, automatic opening and delay closing of the refrigeration system, and multiple protection devices for overheating and overcurrent. The cold liquid in the low-temperature coolant circulator is output to cool or thermostat the experimental container outside the machine or establish a second constant temperature field.
Performance characteristics

1. Adopt air-cooled fully enclosed compressor unit refrigeration, microcomputer intelligent control, refrigeration system automatically open, delay, close, overheating, overcurrent multiple protection device.
2. Internal cold liquid output, cooling or constant temperature outside the experimental container or the establishment of a second constant temperature field.
3. The microcomputer is equipped with a timing shutdown function. After opening this function, the timing shutdown time can be arbitrarily set within 0-100 hours.
4. Double window, red and green color LED display temperature setting value and temperature measurement value, quantity resolution 0.1 ℃, microcomputer can correct temperature measurement value deviation, the digital display accuracy of ± 0.1 ℃.
5. With microcomputer software lock function, can lock the system parameters set value, irrelevant personnel can not change the set parameters.
6. All the above operations can be completed by pressing the touch key on the microcomputer intelligent control instrument, and the operation is simple.
7. The product is easy to use and can work continuously.
8. Adopt air-cooled fully enclosed compressor unit refrigeration and microcomputer intelligent control system to provide low-temperature circulating coolant to meet the needs of cooling water and low-temperature liquid to cool down or constant temperature instruments.
9. The use of stainless steel materials, the water tank can be pre-added with high-quality pure water inside and outside the machine circulation cooling, can ensure the normal operation of precision instruments with high water quality requirements, and extend the service life of precision instruments.
10. It can be used with 2 liter rotary evaporator (dish) instead of tap water condensation, especially suitable for condensing water when low boiling point or heat sensitive materials are evaporated.
