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.
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.
In order to meet your buffer management challenges, opt for buffer quality rather than quantity. Our superior BioPerformance Certified buffers are stringently tested and pre-qualified to expedite your bioprocess workflows in critical life science applications, such as cell culture, molecular biology, and diagnostic manufacturing. This may include testing for nuclease, protease, and phosphatase enzymatic activity, cellular toxicity, or endotoxin and bioburden levels. Using a single high-quality buffer across multiple workflows ensures experiment reproducibility and reduces time, resource costs and even laboratory space – so that you can get on with your research endeavors.
Trying to calibrate the correct concentration and pH value in buffer preparation can be a tedious, time-consuming task for scientists. 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 results that are reliably reproducible again and again. By saving time, effort and even shelf space, you can focus on more important areas of your research endeavors.
