Vivaspin™ ultrafiltration spin columns are designed for fast, non-denaturing concentration and desalting of proteins and other biological samples.

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.
