Description
The CentriPure 96 Gel Filtration Column Array 300 – Z25M by emp BIOTECH offers a fast and scalable solution for the simultaneous desalting and purification of up to 96 biological samples in a single step. Packed with Zetadex-25, a cross-linked dextran-based size-exclusion resin, each column efficiently separates small molecules such as salts, dyes, biotin, haptens, and ammonia from larger biomolecules including proteins (>5 kDa), nucleic acids (>10 bp), and nanoparticles (>2 nm).
Performance Highlights
- >99.99% removal efficiency for low molecular weight contaminants
- >85% recovery of target biomolecules
- ~1.5-fold dilution during processing
- <15-minute total run time
- Gravity-based flow – no centrifuge or vacuum required
Specifications
