Vivaspin™ ultrafiltration spin columns are designed for fast, non-denaturing concentration and desalting of proteins and other biological samples. the target molecule typically exceeding 95%. The entire process is performed in a single tube with an upper compartment containing sample and lower compartment separated by a semipermeable membrane with a molecular weight cut-off (MWCO) selected by the user. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber.
Features and Benefits
Ease-of-use: One-step sample concentration in a single tube, for minimal sample handling and reduced sample loss, as well as pH compatibility over a broad range – pH 1 to 9.Sample protection: Patented Vivaspin dead-stop technology ensures samples cannot be concentrated to dryness and enables direct concentrate recovery.Ease-of-use: One-step sample concentration in a single tube, for minimal sample handling and reduced sample loss.High flow rates: And minimal membrane blockage through the vertical polyethersulfone (PES) membrane design.Minimal protein adsorption: Thanks to the Vivaspin™ polycarbonate tube design.Wide selection: Vivaspin sample concentrators are suitable for sample volumes ranging from 100 μL to 20 mL, with a range of molecular weight cut-off (MWCO) values from Mr 3000 to 100 000.
