Provides rapid, efficient separation of biomolecules- Ultrafiltration is the preferred method for biolomecule purification, fractionation, and concentration as well as for buffer exchange and desalting of samples.Omega™ membrane provides high recovery and typically results in > 90% recovery of target biomolecules- For proteins, it is recommended that a molecular weight cut off of 3-6 times smaller than the molecular weight of the solute being retained be selected. New well design results in faster, more uniform filtration rates across the plate with reduced hold-up volume for maximum sample recoveryIntrinsic plate and membrane properties prevent target molecules from binding to the plate This product is not approved for use in medical, clinical, surgical or other patient applications.
