Centrifugal Filters

Supplier: Sartorius

These centrifugal devices are ideal for the concentration or ultrafiltration of difficult to filter samples, even whole blood or cell lysates.

Supplier: Thermo Fisher Scientific

Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) membrane for concentration, desalting, and buffer exchange of biological samples such as proteins and nucleic acids.

For 0,1 to 1000 ml, Hydrosart® membrane. Vivaflow 50R is a ready to use and reusable laboratory crossflow cassette for applications like cell culture supernatant concentration, virus concentration and water sample concentration. The thin channel, flip flow recirculation path of the modules provides high crossflow velocities with minimum pump speed requirements. A single module with 50 cm² active membrane area typically concentrates 250 ml by a factor of 20 in less than 30 min.

Pierce™ Abundant Protein Depletion Spin Columns are optimised to decrease the abundant albumin and antibody components of human plasma samples in preparation for mass spectrometry or 1D and 2D gel electrophoresis.

Supplier: Thermo Fisher Scientific

These spin columns provide a fast, easy to use format for purifying GST-fusion proteins from cellular lysates. The glutathione is immobilised through its central sulfhydryl onto 6% crosslinked agarose resin. Purification of GST-fusion proteins using glutathione (GSH) agarose beads is well documented and provides a one-step, high purity affinity purification.

Vivapure® Ion Exchange (IEX) spin colums are centrifugal devices. They incorporate Sartobind membrane adsorber technology as their chromatography matrix. Sartobind IEX membrane adsorbers are based on stabilised regenerated cellulose and display a microporous structure with a pore size of >3 μm, which is orders of magnitude larger than conventional chromatographic gel materials.

PAGE-Optimizer™ is a unique, spin column for the preparation of samples for SDS-PAGE. The columns contain a proprietary separation matrix that removes contaminants such as salts, detergents, cellular agents and other common buffering agents. PAGE-Optimizer™ helps eliminate smeared lanes, distorted and/ or smiling bands and swollen lanes. PAGE-Optimizer™ has also been shown to reveal protein bands previously masked by the above interfering agents.

Vivaspin® 100 PES centrifugal concentrators are versatile ultrafiltration units for centrifugation-based sample concentration as well as pressure filtration applications.

Supplier: Cytiva

Vivaspin® sample concentrators are designed for fast, nondenaturing concentration of biological samples by membrane ultrafiltration.

Supplier: Corning

Spin-X® centrifuge tube filters use centrifugation to remove bacteria, particles, or cells from liquids, HPLC sample preparation and DNA removal from agarose or acrylamide gels.

Supplier: G-Biosciences

The 3 ml spin columns are designed to hold up to 3 ml of resin, leaving enough rome for a further 4 ml of buffer. The unique design allows the columns to utilise a 15 ml centrifuge tube as a collection tube, so the columns can be centrifuged for rapid purification.

Supplier: Cytiva

Protein A HP SpinTrap™ columns are designed for the enrichment of proteins of interest, immunoprecipitation and the purification of monoclonal and polyclonal antibodies from cell lysates and biological fluids.

Supplier: Corning

These non sterile centrifugal concentrators offer a simple, one step procedure for concentrating or desalting proteins and other biomolecules with 90% or better recovery.

Supplier: G-Biosciences

These disposable spin columns are designed for protein purification. These spin columns are uniquely designed, with a snap off end converting to a closure for the column for easy manipulation and use.
