Storage Requirements And Shelf Life Of HEPES Buffer CAS 7365-45-9

HEPES (2- [4- (2-hydroxyethyl) -1-piperazinyl] ethanesulfonic acid) is a commonly used biochemical buffer used to maintain the stability of biological systems at ideal pH. Proper storage can ensure the performance and effectiveness of HEPES buffer.

Storage requirements for HEPES buffer

1. Dry storage: HEPES buffer should be stored in a dry environment to avoid being affected by moisture or moisture. A humid environment may lead to a decrease in the quality of HEPES buffer and affect its performance.

2. Storage in a dark place: Prolonged exposure to light may reduce the stability of HEPES. Therefore, it is best to store HEPES buffer in a dark place to reduce the impact of light on it.

3. Sealed storage: After opening the container of HEPES buffer, it should be sealed in a timely manner to prevent moisture and carbon dioxide from entering the container. Consider dividing HEPES into small bottles to reduce the number of times the main container is repeatedly opened.

4. Low temperature storage: Although HEPES is relatively stable at room temperature, long-term storage is best carried out under low temperature conditions. It is usually recommended to store HEPES buffer in a refrigerator at 2-8 degrees Celsius, especially for prepared solutions, and do not place them under high temperature conditions.

5. Avoid contamination: Use clean tools and containers to remove HEPES buffer to avoid contamination from external impurities.

6. Pay attention to labels and dates: Label and date stored HEPES buffer bottles to ensure identification of production and storage times during use, and avoid using expired buffer.

Shelf life of HEPES buffer

The shelf life of HEPES buffer depends on its storage conditions and production quality. Normally, under the correct storage conditions, unopened HEPES buffer powder can maintain its effectiveness for a long time, but it is recommended to check the product's shelf life when purchasing to avoid using expired and counterfeit products. Once used, even if stored in place, there will be significant changes in performance that can interfere with experimental results.

HEPES buffer plays an important role in biochemical experiments, and correct storage is crucial to ensure the reliability and accuracy of the experiment. Adhering to storage requirements such as drying, avoiding light, low temperature, and sealing can ensure the optimal performance of HEPES buffer in experiments. At the same time, choosing a reliable HEPES supplier is also an important step in ensuring the quality of the experiment. Here, you can consider Desheng. As a professional manufacturer of HEPES, it not only has a purity of up to 99%, but also is a powder with good water solubility, ready to use and convenient for storage.
