1. Understand the centrifuge tube

It has been widely used in biological sciences, especially in the fields of biochemistry and molecular biology. Centrifugal technology is mainly used for the separation and preparation of various biological samples. The biological sample suspension is placed in a centrifuge tube under high-speed rotation. Due to the huge centrifugal force, suspended tiny particles (such as organelles, biological macromolecules, etc. are precipitated, etc.) ) settles at a certain speed so that it can be separated from the solution.

Different from conventional test tubes, centrifuge tubes are specially used for centrifugation. Centrifugation refers to spinning a liquid at high speed to separate its components. Centrifuge tubes are essential for this process. So what are the uses of centrifuge tubes? What are the precautions?

2.The use of centrifuge tubes

Instrument Life: Certain laboratory instruments are sensitive to contaminants. Mass spectrometers and high-pressure chromatography units can become clogged with foreign material entering these machines. These instruments work by injecting a small sample of material through a column. Next, the analyte is isolated from the sample and then studied by specialized software. Centrifuge tubes are important to prevent clogging of laboratory instruments. The idea is to use these tubes to separate the analyte from any potential substances that could interfere with the test sample.

Medical samples: When discussing centrifuge tubes, blood tests may come to mind. As the blood cells sink, centrifugation separates the organelles from the blood cells. Centrifugation can also extract DNA and RNA from cells.

Sample Handling: Sometimes contaminants are found in samples that need to be analyzed. The goal of sample processing is to remove contaminants so that the sample can be properly studied. This is where centrifugation is key. The centrifugation process separates the sample from contaminants, leaving a viable sample for study. To further separate the two substances, analysts can use a pipette to remove a liquid sample from the test tube.

3. The role and precautions of the centrifuge tube

Centrifugal tubes are made of plastic, glass or steel according to national standards and pharmaceutical industry standards, which are not easy to be damaged. Generally, steel centrifugal tubes have high strength and are not easy to deform, and also have heat resistance, frost resistance and chemical resistance. The effect of corrosion is applicable to some chemicals. Precautions for centrifuge tubes: When using centrifuge tubes, do not use one tube multiple times. Pay attention to the volatilization of samples and the leakage of some radioactive or corrosive samples; in the storage process, it is necessary to seal them well; Prevent the centrifuge tube from being deformed during use.
