General description

Finding the right chemical that matches your pharma and biopharma manufacturing needs as well as regulatory demands can be a complicated challenge. With our application know-how and regulatory expertise, we support you in every step of development, scale-up, and production.As part of our Emprove® Program, our raw materials are offered with extensive documentation facilitating compliance of your pharma and biopharma product, full supply chain transparency and risk mitigation. Our SAFC® portfolio of high-quality products for pharma and biopharma manufacturing withstands strict quality control procedures and is produced according to applicable cGMP guidelines.

Application

The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.

Packaging

10 kg in Plastic drum
