Centrifuges have the difference between high-speed centrifuges and low-speed centrifuges, and the two types of centrifuges are not only different in name. The rotational speed of the force centrifuge does not exceed 4000rpm, while the rotational speed of the high-speed centrifuge can reach more than 16000rpm. And the scope of application is also different.
High-speed centrifuge:
Generally, a multi-purpose zonal centrifuge is used to separate and collect cells, viruses, and DNA molecules according to the density and gradient of the sample solution.
High-speed centrifuges, in addition to being widely used in production processes, are now widely used in laboratory equipment. Due to the use of a DC variable frequency motor or a DC brushless motor, the speed is generally adjustable and has a high speed.
Low speed centrifuge:
In addition to being used in traditional industries such as textiles, chemicals, and environmental protection, low-speed centrifuges are now widely used in pharmaceutical companies to achieve the separation of mother liquor. Possible pollution or damage or improvement of hygiene, the part in contact with the material is made of stainless steel or the whole is made of stainless steel.
Due to the high speed of the high-speed centrifuge, more careful attention should be paid to the use of the low-speed centrifuge. Usually, the following aspects should be paid attention to:
1. Usually the centrifuge will have a registration form, please register the user, rotor, rotation speed and time before use.
2. The centrifuge tube must be well balanced. , pay attention to the position balance when placing the centrifugal rotor. Never exceed; the maximum speed limit of the centrifuge or centrifugal rotor.
3. The sleeve must reach the preset speed before leaving Li Xinhu: if there is any abnormality, stop it immediately.
