In the laboratory, we often encounter experiments to allow experimental samples to be tested at a specific ambient temperature, either at a constant temperature or at a high temperature. In high temperature constant temperature, we often use high temperature constant temperature oil bath, because the boiling point of oil is very high. If it is water, you can use constant temperature water bath, constant temperature water bath, low temperature thermostat and other instruments. The constant temperature effect of these instruments in water is very high. Significant; if low temperature constant temperature is required, the low temperature thermostat is generally used, not only can keep the temperature low, but with the advancement of technology, the accuracy under constant temperature is also slowly increasing, Shanghai Zhixin ZX series low temperature thermostat The accuracy has reached 0.05.
The advancement of technology and the development of science and technology, these cryostats are also changing dramatically, with higher precision and more precise temperature control. Therefore, there are many problems in the selection. I don’t know what kind of instrument is suitable. Use it yourself, what kind of instrument quality is reliable. Generally, we can consider the following points when choosing a cryostat. I believe that there will be more or less help for your choice.
1. When you open the website or brochure of Shanghai Zhixin cryostat, you can first observe the picture of the instrument. The general instrument first shows you the panel design. Although the quality of the instrument is not directly proportional to the panel design, but one Good instruments, manufacturers are still very concerned about the development, just like the quality of clothes is good, ugly can not sell, look at the material and look at the material.
2. At present, most of the cryostats on the market are made of 304 stainless steel. The exterior is made of simple cast steel. If the instrument is found not to use 304 stainless steel liner or 316 stainless steel liner, you can consider simply looking at it. Because the instrument once involved strong acid and alkali medium, other commonly used stainless steel liners can not bear. If there is no special need, the shell can be selected with the recommended cast steel material, which saves cost compared to the whole machine stainless steel structure.
3. Whether other objects are added in the instrument, because some experiments need to add some objects, such as stainless steel test tube racks for fixing centrifuge tubes, etc., which can be inquired according to your experimental needs. Avoid buying mistakes.
4. Whether there is internal or external circulation, this is very important. In the low temperature constant temperature tank, the internal and external circulation pump is an important guarantee for high precision and constant temperature of the instrument. You can check whether there is a pump cycle button or device on the instrument panel.
5. To consult with Shanghai Zhixin manufacturers about the knowledge and product information of the cryostat, and understand the characteristics and performance of the cryostat to meet the needs of its own laboratory. Now many cold baths are in addition to shape, volume and so on. Things can't change, and many others are very flexible.
6. There are some details of the instrument parameters that need attention, remember not to be sloppy.
7. Buy a low temperature thermostat to Shanghai Zhixin Experimental Instrument Technology Co., Ltd., quality assurance, and perfect after-sales. A wise choice.
