The balance temperature of the centrifuge refrigeration system is also related to the rotor.

Shanghai Xinzhuang Instrument Co., Ltd. develops the LNB brand centrifuge, which is energy-saving and environmentally friendly and domestically leading. Professional manufacturing is more secure and affordable. The selection of materials is exquisite, the craftsmanship is exquisite, the quality is good, the price is reasonable. Since the establishment of the company, it has paid great attention to product development, upgrade and update, and constantly introduces intelligent instruments with good operability and stability, which is the principle that Xinzhuang Instruments has always followed. . At the same time, in order to better serve users, the company is also equipped with professional application engineers to answer your questions at any time.

The following is a detailed description of the issues that should be noted when purchasing precision centrifuges:

(1) Temperature: Some samples (such as proteins, cells, etc.) will be destroyed under high temperature conditions. This is to choose a refrigerated centrifuge. The refrigerated centrifuge has a rated temperature range. The heat generated by the centrifuge at high speed is balanced with the refrigeration system of the centrifuge at a certain temperature (the sample for general freeze centrifugation needs to be kept at 3 ° C ~ 8 ° C), and the specific amount can be related to the rotor, such as a centrifuge The rated temperature range is -10 ° C ~ 60 ° C, the horizontal rotor can be rotated to about 3 ° C, if the angle rotor may only be about 7 ° C. This should also be consulted in detail about the product sales staff and the relevant technical personnel of the production plant.

(2) Rotating speed: The centrifuge is divided into low speed centrifuge (<1 0000 rpm/min), high speed centrifuge (1 0000 rpm/min 30,000 rpm/min) and ultra high speed centrifuge (>30000 rpm) according to the maximum speed. /min), each centrifuge has a rated maximum speed. The maximum speed refers to the speed under no-load conditions, but the maximum speed varies depending on the type of rotor and the quality of the sample. For example, a centrifuge rated at 16,000 rpm/min indicates that the rotor rotates 16,000 times per minute at no load, and after the sample is added, the speed must be less than 16,000 rpm/min. The rotor speed is different, the maximum speed is different (one rotor can be equipped with multiple rotors), the horizontal rotor can reach 1 5000 rpm/min, but the angle rotor can reach 14000 rpm/min. The specific difference should be consulted in detail. The sales personnel and the relevant technical personnel of the production plant, so the choice of the speed should be cautious, the maximum speed of the selected centrifuge is higher than the target speed. For example, the target speed is 16000 rpm/mIn, and the maximum speed of the selected centrifuge must be higher than 16000 rpm/min.
