Description

General description

Our SAFC^® portfolio of high-quality raw materials for use in biopharmaceutical processing withstands strict quality control procedures plus the documentation and expertise to help our customers meet requirements as defined by the M-Clarity Program.

M-Clarity Program

Buffer quality is vital for the success of biopharmaceutical processes, because buffers are indispensable in nearly every production step.

Our broad portfolio of buffer materials manufactured under appropriate controls is tailored to your needs. Ranging from non-GMP grades for low-risk application, to IPEC-PQG GMP for higher-risk applications, we have products covering all your manufacturing needs.

Application

Bis Tris is a commonly used biological buffer for very broad usage in biological systems such as diagnostics, electrophoresis and protein based bioprocessing. The pKa of Bis Tris is 6.36 which makes it a good candidate for biological-based formulations.

Bis Tris is used in a wide variety of biological applications including protein separation buffers, cell culture media, electrophoresis separations and diagnostic reagent formulations.
