We understand the importance of protecting the integrity of your biomolecules and reagents with the right buffering systems. Our biological buffers provide solution stability and pH control without interfering with biological processes, and supply critical salts and nutrients for cells and tissues. Our advanced buffering systems can bring you phenomenal stability in cell culture, polymerase chain reaction (PCR), drug screening, bioprocessing, purification, and final formulation applications. All of our products can be scaled from early research to commercial applications in varying buffer grades. We offer numerous packaging configurations, custom blending, and even liquid formulation.

Complete Workflow Solutions

We also supply a comprehensive selection of high-quality biochemicals in a practical range of grades and in a variety of innovative, user-friendly packaging options. In addition to off-the-shelf products, we offer custom reagent manufacturing, blending and packaging to meet your needs.
