Buffers
Buffers maintain stable pH levels in chemical and biological systems. They are essential in laboratory research, pharmaceutical development, and diagnostic testing to ensure consistent reaction conditions. Commonly used in cell culture, enzyme assays, and protein purification, buffers resist pH changes when acids or bases are added. Molekula stocks a range of buffers with full technical documentation and CoA per batch.
Every product here can be supplied in any quantity. Pack sizes and prices on the product pages are a starting point — tell us what you need and we'll manufacture, source and repack it, from grams to multi-tonne.
