Many biochemical systems and processes can be impaired by relatively small changes in the hydrogen ion concentration. Biological buffers provide solution stability and pH control without interfering with the biological processes of the medium. Moreover, buffers supply cofactors, critical salts, and nutrients essential for the viability of cells and tissues.

Higher Purity for Superior Stability

We understand the importance of protecting the integrity of your biomolecules and reagents with the right buffering systems. We offer an extensive portfolio of biological buffers backed by in-depth scientific knowledge, analytical capabilities, and technical support: strengthened by decades of manufacturing these critical products.

Our high-purity buffers are characterized to assure minimal trace element levels, chemical impurities, and biological contaminants. Due to their impeccable lot-to-lot consistency, our products can be trusted to perform reliably every time. Their high solubility and solution clarity also ensure low background for ultra-sensitive spectroscopic and visual detection.
