Concentrators for Samples up to 500uL

The centrifugal concentrators offer a simple, one-step procedure for concentrating or desalting proteins and other biomolecules with 90% or better recovery.
The vertical membrane design and thin channel filtration chamber minimizes membrane fouling and provides fast, high speed concentrating, even with particle laden solutions

Concentration, desalting of proteins, enzymes, monoclonal antibodies, immunoglobulins
Removal of labeled amino acids and nucleotides
Deproteinization of samples
HPLC sample preparation
Recovery of biomolecules from cell culture supernatants, lysates
Concentrating virus from cell culture medium

Integrated dead stop design eliminates the risk of spinning to dryness; no respinning necessary
Choice of three sizes for greater flexibility
Low binding polyethersulfone (PES) membranes are available with five molecular weight cut-offs (MWCO): 5K, 10K, 30K, 50K, and 100K to meet all your concentrating needs. Note: Choose an MWCO one-half to one-third smaller than the protein to be concentrated
The MWCO and graduations are printed right on the side of the concentrator tube to avoid confusion
