    Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%. Patented dead-stop technology ensures that samples cannot be concentrated to dryness and enables direct concentrate recovery.

    • Accept sample volumes from 100µLto 20mL, with a range of molecular weight cutoff values from Mr3000 to 100,000
    • Vertical polyethersulfone semi-permeable membrane separating upper and lower chamber resists blockage and tolerates high flow rate
    • Centrifugation forces solvent through membrane, leaving concentrated sample in the upper chamber
    • Compatible pH range: 1 to 9
    • Active membrane area: 0.5cm2

    For maximum recovery, select a MWCO at least 50% smaller than the molecular size of the species of interest.
