Sartorius Vivaspin 500, MWCO 300 kDa, polyethersulfone, 25 pcs

Vivaspin centrifugal concentrators offer the optimal solution for applications where protein solutions are concentrated or buffer solutions are exchanged. Through the membrane made of polyethersulfone (PES), their important macromolecules (e.g. proteins, DNA, antibodies, etc.) are retained, while unwanted by-products such as salts, solvents and small organic molecules pass through it. This ensures not only purification of the desired protein solution, but also its concentration.
The patented Dead-Stop technology allows direct recovery of the concentrate without any further processing steps. This makes sample work safe and convenient.
Other applications include: - Forensic DNA sample purification - Peptide fractionation - Removal of unwanted primers from PCR products - Removal of specific amino acids and nucleotides - General laboratory work such as concentration, desalting, filtration, purification Note: For high recovery of the desired proteins, it is advisable to choose a membrane containing at least half the molecular size of the target protein.
For 100 to 500 µl sample solution.
Tubes fit all standard fixed rotors for 1.5 and 2.0 ml reaction tubes.
