Vivaspin® 4 Centrifugal Concentrator

Vivaspin® 4 Centrifugal Concentrator

Up to 4 ml starting volume
Concentrate up to 200x
Vivaspin® 4 ml concentrators are disposable ultrafiltration devices for the concentration of biological samples. Maximum initial sample volumes range up to 4 ml. They can be effectively used in either swing bucket or fixed angle rotors accepting 15 ml centrifuge tubes.

The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimises membrane fouling and provides high speed concentrations, even with particle laden solutions.

Vivaspin® 4 is available with the high flux polyethersulfone membrane range which is recommended for most solutions.
