Standards required for high-quality biological buffers

 

Biological buffer is usually an indispensable regulator in many production and experimental fields, which can slow down the change of pH when adding a certain amount of other substances. Biological buffers usually exist in the form of powder when they leave the factory, and there are many manufacturers on the market who prepare them as solvents for resale. However, compared with powder, solvent is not as convenient as powder in transportation and storage. Now let's learn more about buffer solution.

 

Characteristics of high-quality buffer solution

1. Good water solubility, simple configuration;

2. The product has high purity and good chemical stability;

3. High buffer capacity within the required pH range;

4. Good compatibility with analytical and experimental application conditions;

5. It has good compatibility with other solutes.

 

There are dozens of biological buffers on the market. Zui is popular in the market with pKa value close to neutral. Here are three commonly used buffers.

 

1. Phosphate buffer: PH value ranges from 5.8 to 8.0. Its advantage is that the PH value will not change with the change of temperature. And the price is cheap, no obvious absorption of ultraviolet;

 

2. Mops buffer solution: PH value is between 6.5 and 7.9, which has the advantage of good stability and high buffer capacity within the physiological PH range;

 

3. Tris buffer solution: The pH value is 7.2-9.0, which has no obvious absorption of ultraviolet light, is relatively cheap, and has a wide buffer range. It can be used in a variety of production and experiments.

 

The quality of the buffer produced by Desheng Biochemical Institute is stable and reliable. The purity of conventional products can reach more than 99%. For a long time, Desheng Biochemical Institute has been committed to the research, development and production of biological buffers. It not only has its own research, development and production team, but also has a professional after-sales service team. We have established long-term cooperative relations with many customers at home and abroad. If you need to use the biological buffer, please feel free to contact us for consultation and purchase!
