4-Hydroxyethylpiperazine ethanesulfonic acid (HEPES) is a zwitterionic buffer, white crystalline powder, soluble in water, it is a weak acid, its pH buffer range is 6.8-8.2, it is important in biochemical industry Biochemical preparations are also considered to be one of the important buffers in the field of biological research. To
As a veteran company with more than ten years of experience in producing HEPES, Desheng, the confidence we give to customers comes from our advantages in all aspects of products:
1. Advantages of PH range:
The suitable culture environment for most cells is pH 7.2-pH 7.4, and the application range of Desheng HEPES buffer just falls between pH 6.8-pH 8.2, which is in line with the characteristics of the pH value needed for cell culture.
2. Purity advantage:
Desheng HEPES has a purity of ≥99%, good water solubility, stable process, and can control a constant pH range for a long time. According to your application needs, we can provide a full range of product testing and special testing services.
3. Advantages of reserves:

4. Export advantages:
Desheng is a professional manufacturer of biological buffers, with strong logistics capabilities and rich export experience. We export to more than 100 countries and have established a long-term cooperation intention.
5. HEPES packaging advantages:
We can pack in quantities according to customer needs. Generally, there are 500g small bottles and 25kg cardboard drums. The big packaging is covered with plastic bags, the white powder is packed in the belt, and the tie is tight.
6. Recommended storage:
HEPES powder is resistant to high temperatures and has a melting point of up to 200°C, so it will not be degraded by autoclaving. However, if the HEPES aqueous solution is exposed to ambient light for three hours, cytotoxic hydrogen peroxide (H2O2) will be produced. Therefore, it should be noted that the HEPES aqueous solution must be kept away from light to avoid affecting the experimental results. HEPES powder is generally placed in a dry room when it is placed, and cannot be exposed to direct sunlight for a long time. It is best to store it at room temperature 2-8°C.
Only after using a good product can you know whether it is a good product in your mind. Desheng is not a company that only manufactures products once. What we want is the trust and support of our customers. We recommend that you use our trial pack first when purchasing the product. Because we firmly believe that quality is the greatest sincerity to give back to customers.
