How to use microcentrifuge tubes and precautions
How to use microcentrifuge tubes
1. Because the graduated centrifuge tube is a measuring device, it must be cleaned and dried before use.
2. When reading, be sure to observe the meniscus correctly, otherwise certain errors will be introduced.3. When using, the number of centrifuge tubes should be determined according to the type of centrifuge. If a centrifuge with double casings is used for a single test, the same volume of liquid must be placed in the other centrifuge tube to maintain balance.
4. The centrifuge tube and the centrifuge casing should be matched. The tube should not be too long, otherwise it is easy to break when turning. But it is not easy to be too short, too short tubes are unstable when rotating in the air, and are prone to breakage. If the sleeve is too thick, it will not enter, and if it is too thin, it will be unstable when rotating. The round mouth should be larger than the inner diameter of the sleeve.
5. After the centrifuge tube is put into the casing of the centrifuge for stratified separation, it should be stopped naturally when it stops rotating, and it must not be forced to stop by external force.
Precautions for Microcentrifuge Tubes
When using centrifuge tubes, do not use one tube for multiple times. Pay attention to the volatilization of samples and the leakage of some radioactive or corrosive samples; during the storage process, it is necessary to seal them well; to prevent the centrifuge tubes from being used during use Deformation occurs.1. Do not put any substance on the centrifugal cover. After each use, be sure to clean the inner cavity and rotor.
2. If the high-speed microcentrifuge has not been used for a long time, the centrifuge cover should be opened for a period of time before use, and the inner cavity should be dried.
High-speed microcentrifuge is a conventional laboratory centrifuge, widely used in biology, chemistry, medicine and other scientific research, education and production departments, suitable for rapid separation and synthesis of trace samples.
Summary: How to use microcentrifuge tubes and precautions. After reading this article, you should have a basic understanding and understanding, I believe everyone understands it! In general, I hope it will be helpful to everyone.
