The laboratory centrifuge is controlled by microcomputer, DC brushless motor drive, stable operation, low noise, high speed precision, touch panel, programmable operation, host operating parameters can be set and automatically stored according to requirements, equipped with electronic door locks, with doors Cover self-locking, overspeed and other protection functions, fault automatic alarm function, the body is made of steel structure, safe and reliable, easy to use. It is widely used in experiments and scientific research in the fields of biology, chemistry, medicine, agriculture and forestry, food safety, blood stations, clinical trials, etc.

The centrifuge tube is an important part of the multi-tube centrifuge. Whether it is suitable or not directly affects the use effect. Let's take a look at what classifications are available.

According to the material can be divided into: plastic centrifuge tube, glass centrifuge tube and stainless steel centrifuge tube.

The centrifuge tubes commonly used in laboratories are plastic and glass. Generally, plastics are used more because the glass tubes cannot be used in high speed or ultra centrifuges.

Plastic centrifuge tubes are available in PP (polypropylene), PC (polycarbonate), and PE (polyethylene). The performance of the pipe of PP is relatively good. The plastic centrifuge tube is transparent or translucent, so that the sample can be visually observed, but it is easy to deform, and the corrosion resistance against organic solvents is poor, so the service life is short.

According to the capacity, it can be divided into: micro centrifuge tube, small volume centrifuge tube and large volume centrifuge tube.

Generally, a centrifuge tube having a capacity greater than 100 mL is referred to as a centrifuge bottle. According to the capacity of the centrifuge tube, the capacity of the centrifuge tube is usually 1.5ml, 2ml, 5ml, 10ml, 15ml, 50ml, etc. The current domestic centrifuge tubes are mainly based on the above specifications, among which are more commonly used more is 10ml and 50ml.

According to the shape of the bottom, it can be divided into a round bottom and a pointed bottom, and a screw cover and a cover.

The screw cap of the screw cap has a finer scale, and the cap has only one overall capacity indication.

According to the cover classification, the cover of the centrifuge tube is generally covered with a small volume of the centrifuge tube, while the ordinary capacity of the centrifuge tube is not only covered, but also has a cap and a screw cap. The centrifuge tube with a capacity of 50 ml or more is basically Mainly with a screw cap. Generally speaking, there is a marking scale at the wall of the centrifuge tube with the lid, and the centrifuge tube of the screw cap has a finer scale, and the lid has only one overall capacity indication.

When using a centrifuge in the laboratory, we need to choose the right centrifuge tube according to our needs.
