It’s important to protect the integrity of your biomolecules and reagents by choosing the right biological buffer systems. We offer an extensive portfolio of biological buffers for a wide variety of applications, including cell culture buffers, PCR buffers, HEPES buffers, and assay buffers.
Key features of our advanced buffer systems:
Our advanced buffering systems can bring phenomenal stability to your cell culture, polymerase chain reaction (PCR), drug screening, bioprocessing, purification, and final formulation-based applications. All our products can be scaled from early research to commercial applications.
We provide a comprehensive selection of high-quality biochemicals in a wide range of buffer grades and innovative, user-friendly packaging options. In addition to off-the-shelf products, we offer custom reagent manufacturing and customized blending.
Our superior BioPerformance Certified buffers are stringently tested and pre-qualified to expedite your bioprocessing workflows in critical life science applications, such as cell culture, molecular biology, and diagnostic manufacturing. This may include enzymatic assay of nuclease, protease, and phosphatase, cellular toxicity, or endotoxin and bioburden levels. Using a single high-quality buffer across multiple workflows ensures the reproducibility of your experiment.
Trying to get the correct concentration and pH value in buffer preparations can be a tedious and time-consuming task. Our pHast Pack™ ready-to-use buffers are specially designed to simplify your work. Simply mix the precisely pre-weighed packets with distilled water for quick and reproducible results again and again. By saving time, effort and even shelf space, you can focus on more important areas of your research endeavors.
