Fast filtration and highly reproducible performance
Use in fixed-angle rotors for 1.5 mL tubes
Removal of particles and precipitates from aqueous and some solvent-based samples
Ideal for use with protein and nucleic acid solutions
Ultrafree®-MC (0.5 mL) and Ultrafree®-CL (2 mL) centrifugal devices are single-use, disposable filters used for removing particulates from aqueous biological solutions. These devices are available in two processing volumes with a range of microporous membranes (from 0.1 to 5.0 µm) for fast filtration and highly reproducible performance. Pre-sterilized units are also available. Use in fixed-angle rotors for 1.5 mL tubes (-MC) and 15 mL tubes (–CL).
