Microsep™ Centrifugal Devices

Precise, quick recovery of microliter volumes of concentrate from starting volumes of up to 3.5 mL

Fast recovery. Achieve 100x concentration and greater than 90% recovery in just minutes.
Available with low protein-binding Omega™ membrane.
Microsep device has deadstop to prevent samples from spinning to dryness.
Ultrasonically welded seal prevents solution bypass.
Versatile. Omega membrane available in a variety of MWCOs color coded for easy identification.

Concentrate dilute protein samples prior to electrophoresis.
Buffer exchange and salt removal.
Remove proteins and particulate from samples for HPLC analysis of drugs, amino acids, and antibodies.
Isolate low molecular weight compounds from fermentation broths for natural product screening.
Recover biomolecules from cell culture supernatants or lysates.
