Hydrophobic Interaction Chromatography Columns for the Separation of Large BiomoleculesHydrophobic Interaction Chromatography separates biomolecules in a decreasing salt gradient, based on differences in surface hydrophobicity. This method preserves the biological activity of proteins. The HIC separation mechanism is complementary to those of ion-exchange and gel filtration chromatography.The ProPac® HIC-10 column is a high-re…

ProSwift™ ConA-1S Affinity Column for Glycan, Glycopeptide and Glycoprotein Enrichment and Purification The ProSwift ConA-1S affinity monolith column is unsurpassed for fast, highly efficient enrichment and purification of Concanavalin A (Con A) binding glycans, glycopeptides, and glycoproteins from complex samples.The HPLC- compatible ProSwift ConA-1S affinity column maintains the specificity and selectivi…

Monolith Reversed-Phase Columns for High-Resolution Protein Separations at High Flow Rates ProSwift® reversed-phase monolith columns uniquely provide the advantages of high resolution at exceptionally high flow rates for protein separations. They deliver the outstanding resolving power of nonporous analytical media combined with faster separations than any bead based columns available. ProSwift polymer monolith columns achieve…

Monolith Ion-Exchange Columns for Superior High-Resolution Analytical and Preparative Protein Separations The ProSwift SCX monolith column line has been expanded to include a new 1 x 50 mm column. As with all ProSwift monoliths, the fast mass transfer allows for fast protein separations. ProSwift monoliths offer excellent separations using fast gradients at low and high flow rates, which improve productivity.ProSwift Monolith…

o   Improved reproducibility, efficiency and column lifetimeso   Range of stationary phases to optimize selectivityo   Powerful resolution, even on short column lengths Product detail:BioBasic SEC columns are available in four pore sizes (60, 120, 300 and 1000Å) to cater for separations of samples from 100 to 10,000,000 molecular weight.  The columns are based on porous silica particles coated with with a hydrophillic polymer…

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart
