What should be paid attention to when using the cryogenic centrifuge tube rack

The low-temperature centrifuge tube rack is a basic experimental instrument in a chemical laboratory used to place (sometimes place test tubes on a test tube rack to observe the phenomenon of an experiment) and dry test tubes in a chemical laboratory. A corresponding number of small wooden posts and small holes are attached to the test tube rack. If there is a small hole, the test tube can be placed upright for use or to continue to observe the progress of the reaction. If there is a column, put the cleaned test tube upside down to allow it to dry.
Low-temperature centrifuge tube racks are common in hospital laboratories and chemical laboratories. They are welded by spot welding and argon arc welding technology. They are products of high quality and price in a true sense.

Low temperature centrifuge tube rack maintenance:
1. Wipe the surface of the centrifuge and the inner cavity of the centrifuge with a wet towel at regular intervals, cut off the power before cleaning, remove the rotor, disinfect with 70% alcohol or clean with a neutral detergent.
2. Wipe the rotor with a damp cloth at regular intervals, and wash the centrifugal hole downward with a bottle brush and hot cleaning solution to prevent the centrifugal residue from corroding and damaging the rotor and sleeve. After cleaning, place the centrifugal tube hole down on the cloth to dry , Do not put the rotor in the washing liquid during washing.
3. The motor shaft is cleaned and lubricated regularly to prevent rust.
4. When the centrifuge is ready for use, the power supply should be cut off.
Precautions for the use of cryogenic centrifuge tube racks
①. There are corresponding number of small holes in the cryogenic centrifuge tube rack for placing test tubes. If there is a hole, the test tube must be placed upright so that you can continue to observe the progress of the chemical reaction in the later period.
②. If there is a column, put the cleaned test tube upside down for drying.
③, pay attention to keep clean.
④. The cleaned test tubes should be placed upside down on the test tube rack for drying.
