Laboratory cryogenic coolant circulation pump precautions
Because of the high uniformity of the temperature field due to its own circulating system, cryogenic coolant circulating pumps are increasingly used in cryogenic coolant circulating pumps. The Sino-brand DL series cryogenic coolant circulating pump adopts an air-cooled totally-enclosed compressor refrigeration and microcomputer intelligent control system to provide low-temperature circulating cooling water (liquid) flow or low-temperature constant-temperature water (liquid) flow to meet the use of cooling water and low temperature Liquid to cool or thermostatic instruments, widely used in petroleum, chemical, pharmaceutical, life sciences, metrology, light industry, and scientific research and other fields. What are the precautions for using a cryogenic coolant circulating pump? [1] Liquid medium (pure water, alcohol, and antifreeze solution) should be added to the tank before using the low temperature coolant circulating pump. The medium liquid surface should not pass through the cooling coil in the tank and should be less than 20mm below the table. [2] Power: 220V 50Hz, power supply power should be greater than the total power of the instrument, the power supply must have a good "grounding" device; [3] Avoid acid-base substances entering the tank to corrode coils and liners. [4] The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument. [5] Always observe the level of liquid in the tank. When the liquid level is too low, add liquid medium in time. [6] When the operating temperature of the low-temperature coolant circulating pump is low, care should be taken not to open the upper cover and not to enter the tank in order to prevent frostbite; [7] After use, all switches are turned off and the power is turned off. [8] During the external circulation of the liquid, the customer should pay special attention to the firmness of the outlet pipe to prevent it from falling off to prevent the liquid from leaking out. [9] The instrument should be cleaned regularly. If it is not used for a long time, empty the media in the tank and clean it to keep the work table and the operation panel clean; Poly mesh Net Bags are a type of packaging material that is made from a lightweight, durable, and flexible plastic material. They are commonly used in the agricultural industry to package and transport produce such as fruits and vegetables.

The purpose of poly mesh net bags is to provide a breathable and protective packaging solution that allows air to circulate freely around the produce. This helps to prevent moisture buildup and the growth of bacteria, which can cause spoilage and reduce the shelf life of the produce.
Poly mesh net bags come in a variety of sizes, colors, and configurations to meet the specific needs of different types of produce. They are typically designed with a drawstring closure or a twist-tie closure to keep the produce securely inside the bag during transport and storage.
In addition to their use in the agricultural industry, poly mesh net bags are also used in other industries such as seafood, poultry, and industrial applications. They are a cost-effective and environmentally friendly packaging solution that can be easily recycled or disposed of after use.
