Descripción
Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%. Patented dead-stop technology ensures that samples cannot be concentrated to dryness and enables direct concentrate recovery.
- Accept sample volumes from 100μLto 20mL, with a range of molecular weight cutoff values from Mr3000 to 100,000
- Vertical polyethersulfone semi-permeable membrane separating upper and lower chamber resists blockage and tolerates high flow rate
- Centrifugation forces solvent through membrane, leaving concentrated sample in the upper chamber
- Compatible pH range: 1 to 9
- Active membrane area: 1.2cm2
- Vivaspin 2 offers easy, contact-free storage by reverse spinning the concentrate into the recovery cap
For maximum recovery, select a MWCO at least 50% smaller than the molecular size of the species of interest.
