Description
Rapid purification and desalting of nucleic acids, proteins, and nanoparticles
The CentriPure 300 – Z25M from emp BIOTECH is a gravity-driven gel filtration column designed for fast and efficient purification and desalting of biological samples up to 30 mL. Packed with Zetadex-25, a cross-linked dextran-based size-exclusion resin, the column efficiently separates small molecules such as salts, dyes, biotin, ammonia, and haptens from larger biomolecules including nucleic acids (>10 bp), proteins (>5 kDa), and nanoparticles (>2 nm) in a single step.
Performance Highlights
- >99.99% removal of small molecule contaminants
- >85% recovery of target biomolecules
- ~1.5-fold sample dilution
- <15-minute processing time
- Gravity flow — no additional equipment required
Specifications
- Resin: Zetadex-25 (50–150 µm particle size)
- Sample volume: 30 mL
- Format: Single-use hydrated column
Applications
- DNA/RNA purification and desalting
- Protein purification
- Buffer exchange
- Nanoparticle cleanup
Why Choose CentriPure?
Designed for mid-scale workflows, the CentriPure 300 – Z25M combines speed, reliability, and high-purity results in one simple step. Its compatibility with a wide range of biomolecules and formats makes it ideal for molecular biology, proteomics, and bioprocessing labs seeking a fast and reproducible alternative to conventional purification methods.
