High-speed refrigerated centrifuge is a commonly used centrifuge product, which is mainly used for rapid separation of mixed liquids. It is widely used in biochemistry, genetic engineering, life science, genetics, medical and other units for laboratory, biochemical tests, separation and suspension. Liquid and other work. I have summarized the instructions for using a high-speed refrigerated centrifuge, and hope to help users better understand and apply the product.
To understand high-speed centrifuges, first understand what a centrifuge is.
A centrifuge is a machine that uses centrifugal force to accelerate the separation of different substances that need to be separated. Mainly divided into two categories of decanter centrifuges and filter centrifuges. The main principle of the decanter centrifuge is to accelerate the sedimentation velocity of different specific gravity components (solid phase or liquid phase) in the mixture by the powerful centrifugal force generated by the high-speed rotation of the rotor, and to separate the different sedimentation coefficients and buoyant density substances in the sample. The main principle of the filter centrifuge is to accelerate the liquid phase in the solid-liquid mixture to the drum by the centrifugal force generated by the high-speed centrifugal drum (with appropriate filter material), and leave the solid phase in the drum. , to achieve the effect of separating solids and liquids, or commonly known as dehydration.
What is a high speed refrigerated centrifuge?
As the name implies, the high-speed refrigerated centrifuge is a centrifuge with a very fast speed (speed above 10,000 rpm) and a freezing function. In addition to the performance and structure of the refrigerated centrifuge, the angle rotor used in the high-speed refrigerated centrifuge is different from the ordinary centrifuge, and is usually made of titanium alloy or aluminum alloy, and the centrifuge tube is made of polyethylene hard plastic.
The role of high speed refrigerated centrifuge
The high-speed centrifuge can separate, concentrate, refine and extract suspended substances in the sample solution, and is mostly used for separation preparation and collection of blood, cells, enzymes, proteins, viruses, hormones, and the like.
Classification of high speed refrigerated centrifuges
High-speed refrigerated centrifuges can be divided into desktop high-speed refrigerated centrifuges and vertical high-speed refrigerated centrifuges.
High Speed Centrifuge features
The high-speed refrigerated centrifuge is characterized by editing microcomputer control and DC brushless motor. It is a special equipment for rapid separation of mixed liquids. It can be widely used in scientific research life science biochemical genetic engineering genetics medical and other units to conduct biochemical test separation and suspension. Liquid and other work. The machine is easy to operate and has a fast cooling speed. It is suitable for experiments with low separation, high centrifugal requirements and low temperature.
High speed refrigerated centrifuge operating procedures
1. Centrifuge sample density should be the same, keep 3mm away from the tube mouth.
2. Place the centrifuge tube with the same density, trim and tube wall in a symmetrical state into the hanging basket. Tighten the corresponding test tube cover and hang it on the corresponding hanging basket. The empty basket should also be hung. Uniform force, otherwise serious laboratory accidents with broken shafts may occur during operation.
3, covered with a high-speed refrigerated centrifuge cover
4, open the switch
5. Place the rotor hanging the basket straight down on the shaft sleeve to ensure it is firm.
6. Tighten the rotor cover.
7. Press and hold the specified position to push the door cover down.
8. Centrifugal parameter setting: speed, time, rotor type, temperature, lifting speed frequency (automatic rotor recognition function is now available for the switch model function)
9. Confirm that the parameter setting is correct. Press START to start, and the user can leave after the high-speed refrigerating centrifuge reaches the set speed for 5 minutes. Observe whether the instrument is working properly during the centrifugation.
10. After the centrifugation is finished (or press STOP to finish the operation), after the rotor stops running, open the door cover, loosen the rotor cover, take the rotor out and put it on the special frame. 14 Take out the hanging basket and take out the sample.
11. The hanging basket is open at the designated position. If there is liquid leakage, take out the sealing ring, wash it and then put it on the tablecloth.
12, turn off the instrument power
13. Clean the condensate in the centrifuge chamber
The above is the introduction and operation process of the high-speed refrigerated centrifuge for everyone to read and share.
High-speed refrigerated centrifuge notes
Because of the very high speed of the high-speed refrigerated centrifuge, once the accident is very serious, in general, the staff can be on the side until the end of the high-speed refrigerating centrifuge. Once you find an abnormality, press the stop button immediately. Do not turn off the power directly, otherwise the instantaneous speed reduction function will be invalid.
