Application Of Biological Buffer Caps

In biological experiments, there is a very important pH stabilizing reagent, which is the biological buffer caps. In the experiment, we usually choose the appropriate weak acid and its conjugated base to get the appropriate pH value. In a large number of experiments, it has been proved that most biological reactions occur under neutral conditions. Generally, the pH value is between 6-8, and the effective buffer range of buffer is between 6-8. Therefore, the acid-base form of buffer should not chelate with some metal ions.

Caps, also known as 3-cyclohexylaminopropanesulfonic acid, is a kind of biological buffer, which can be used for enzyme chemistry and HPLC separation of basic drugs. The appearance is white crystal or powder, caps can be dissolved in water, pH buffer range is 8.9-10.3, pKa value is 9.6, molecular weight is 243.28, CAS number is 1135-40-6 below 25 â??.

Desheng bio has been developing and producing biological buffer for many years, and has rich experience. Caps is the core product, which is highly praised in the field of biochemical diagnostic reagents and the market of new paint products. Desheng has been established for decades. The company's products are sold to more than 100 countries around the world. The product quality is good and the price is more favorable. If you are interested, you can call us.

RE-100L rotary evaporator is mainly used in the concentration, crystallization, drying, separation and solvent recovery of pharmaceutical, chemical and biological pharmaceutical industries. Its principle is: under vacuum condition, constant temperature heating makes the rotary bottle rotate at constant speed, and the material forms large area film on the bottle wall, so it can be evaporated efficiently. The solvent evaporation is cooled by the high-efficiency glass condenser and recovered in the collecting bottle, so as to greatly improve the evaporation efficiency. The utility model is especially suitable for concentrating and purifying biological articles with high temperature and easy decomposition and degeneration.
