VWR® Centrifugal Filters

Use to concentrate, purify, and desalt peptides, proteins, oligonucleotides, DNA, and RNA; clean up labeling and PCR reactions; isolate DNA from agarose gel slices; buffer exchange; separate proteins, oligonucleotides, and RNA from acrylamide gels; clarify samples; or remove particulates. Filter housings are constructed of polypropylene and are available with a polyethersulfone (PES) or nylon membrane. Filters with nylon membrane are ideal for prefiltration clean-up of large agarose or acrylamide gel debris prior to further purification with an MWCO device.
