Biological Buffers

Biological Buffers

J.T.Baker brand biological buffers from Avantor are specifically engineered for biotechnology, cell biology and molecular biology applications, including biopharmaceutical production. All our cGMP-manufactured biological buffers meet USP requirements and EP specifications, as well as our own stringent criteria.


J.T. Baker® brand biological buffers are non-toxic to cells, are not absorbed through cell membranes, and feature pKa values at or near physiological pH to help stabilize the product as it goes through the many steps required in the purification process. These buffers are part of the ULTRAPURE BIOREAGENT family and are characterized by high assay, low insolubles and low heavy metals, and the absence of DNase, RNase and protease.
