Biological buffer is a chemical product that is refined from some crude chemical products under high temperature conditions under certain pressure and catalyst action through multi-step chemical unit operations. It is an important chemical product in biochemical research and is also used in many fields such as clinical laboratory diagnostic reagents, life science research, pharmaceuticals, and biotechnology. Basic Introduction to BES Sodium Salt There are dozens of types of biological buffering agents, among which BES sodium salt is one. Its full name is N, N-di (2-hydroxyethyl) -2-aminoethanesulfonic acid sodium, CAS number: 66992-27-6, and the effective pH range is between 6.4 and 7.8. The refined BES-NA has a high purity and is a white powder with a purity of up to 99%. When used, it needs to be dissolved in deionized water, and after water dissolution, it becomes a colorless and transparent liquid. Application of BES sodium salt BES sodium salt powder does not chelate with metal ions and does not react with any components of the medium, so it has certain advantages in biochemical experiments. It has irreplaceable advantages in both cell culture and mammalian cell transformation, and also plays a certain role in other biochemical fields. Precautions for using BES sodium salt 1. In the configuration or experiment, attention should be paid to the sterilization of the containers, water, and other additives used to avoid other influencing factors on the experiment; 2. BES-Na powder is harmful to human health. Direct contact and inhalation of dust related to materials should be avoided, and relevant protective equipment should be worn when using it; 3. It is best not to store too much of the prepared solvent, as ready to use results are the best. The BES sodium salt and other biological buffering agents currently produced by Desheng are white powder in appearance, which is one of the standards for testing the quality of a product. The higher the purity, the purer the color. The purity of biological buffering agents produced by Desheng can now reach 99%. If you need to purchase them, please feel free to inquire and order.
