*** Product Update ***
CentriPure MINI is now ZetaSpin MINI
We are pleased to announce that our popular desalting and buffer exchange spin column, previously named CentriPure MINI, has been renamed to ZetaSpin MINI.
The product itself remains
unchanged—precision-packed with Zetadex, our high-quality cross-linked dextran manufactured in an ISO-13485 environment. Available formats include Zetadex-25 (MWCO for globular proteins >5 kDa or oligonucleotides >10 bp) or Zetadex-50 (MWCO for globular proteins >25 kDa or oligonucleotides >20 bp).

Choose from pre-hydrated columns (water, TRIS, or PBS) or dry resin to hydrate with your own buffer for direct elution into your desired formulation.
Ideal for a wide range of applications, including removal of free dye or radiolabel after labeling reactions, oligonucleotide desalting, and buffer exchange for protein and antibody samples.
Try ZetaSpin MINI in your lab with a free sample pack of 4 spin columns. Order by April 30 to qualify. Limit one sample pack per product per customer.
