GE Healthcare Introduces Vivaspin™ Sample Concentrators for Protein Sample Prep
Product News May 05, 2008
GE Healthcare has announced that it is introducing Vivaspin™ sample concentrators for protein sample prep, offering concentration of biological samples with minimal membrane blocking and no risk of concentration to dryness.
The company claims that the Vivaspin can provide fast, nondenaturing concentration of up to 30 times from a range of volumes between 100 µl to 20 ml.
Sample concentration using Vivaspin is performed by membrane filtration in a single tube and the molecular weight cut-off of the membrane can be selected by the user.
The sample is placed into the upper compartment of the tube, and centrifugation is applied to force solvent through a semipermeable membrane into the lower compartment of the tube. This leaves a more concentrated sample in the upper chamber.
The new Vivaspin sample concentrators are available now from GE Healthcare.
