Do you know how to choose the appropriate centrifuge tube？

Centrifuge tube is a common experimental consumable in the laboratory, mainly used in conjunction with the centrifuge. Generally, manufacturers of centrifuges will produce corresponding centrifuge tubes, mainly to ensure the overall safety of the host, rotor and centrifuge tubes.

Centrifuge tube is a kind of tubular sample container, which can be equipped with a sealing cover or a gland. It uses centrifugal technology to generate strong centrifugal force when the object is rotated at high speed, so that the suspended particles placed in the rotating body will settle or float, thereby causing a certain These particles achieve the purpose of concentration or separation from other particles.

At present, centrifuge tubes in the market can be divided into plastic centrifuge tubes, glass centrifuge tubes and steel centrifuge tubes according to their materials. Different types of centrifuge tubes are suitable for different application scenarios.

Plastic centrifuge tube

The advantage of the plastic centrifuge tube is that it is transparent or translucent, and the hardness is small. The gradient can be taken out by the puncture method. The disadvantage is that it is easily deformed, has poor resistance to organic solvents, and has a short service life. The plastic centrifuge tube can be equipped with a tube cover, its function is to prevent the sample from leaking, especially when it is used for radioactive or highly corrosive samples, it is very important to prevent the sample from leaking; the tube cover also has a function to prevent samples Volatilize and support the centrifuge tube to prevent deformation of the centrifuge tube. When selecting this point, pay attention to check whether the tube cover is tight, and whether it can be closed tightly during the test, so as to achieve no leakage when it is inverted.

Glass centrifuge tube

When using glass tubes, the centrifugal force should not be too large. Rubber pads are needed to prevent the tubes from breaking. High-speed centrifuges generally do not use glass tubes. The cap of the centrifuge tube is not well sealed, and the liquid cannot be filled up (for high-speed centrifuges and angle rotors are used) to prevent overflow and loss of balance. The consequence of spillage is to contaminate the rotor and centrifugal chamber and affect the normal operation of the sensor. During ultracentrifugation, the liquid must be filled with the centrifuge tube, because ultra-separation requires a high vacuum, and only by filling it can the centrifuge tube be deformed.

Centrifuge tubes can be divided into the following specifications according to their size: 1.5/2/5/10/15/50/100/250/500/mL, etc. Centrifuge tubes generally have these specifications, and many of them are used That is 1.5mL, 10ml and 50mL. In addition, the centrifuge tube has a round bottom and a pointed bottom, as well as a screw cap and a plug cap. The screw cap centrifuge tube has a fine scale, and the plug cap has only an overall capacity indicator.

Centrifuge tubes commonly used in laboratories are plastic and glass, and generally plastic is used more.
