Ultrafree-MC microcentrifuge filters 

Use in any standard fixed-angle microcentrifuge rotor.

Units consist of microcentrifuge tube with hinged cap and filter insert. The microporous membrane units (with pore size specified) are useful for clarifying and sterilizing small volumes quickly and conveniently. The ultrafiltration membrane units (with nominal molecular weight cut off −MWCO − specified) are for concentrating solutions of macromolecules or for removing macromolecules from solution.
