Vivaspin™ ultrafiltration spin columns for minimal handling and reduced sample loss. Specially designed for rapid, non-denaturing concentration and desalting of proteins and other biological samples. Vertical polyethersulfone (PES) membrane minimizes membrane clogging to ensure high flow rates.
Features & Benefits:
- Dead-stop technology: samples are not concentrated to dryness and allows direct concentrate recovery
- pH compatibility from pH 1 to 9
- Polycarbonate tube design for minimal protein adsorption
- Suitable for sample volumes from 100 µl to 20 ml with a molecular weight cutoff value of Mr 3000 to 100 000
