Rubber and Silicone Tubing
Research Products International Corp JTR Press-to-Seal Silicone Isolators, 2.5mm Thick, 20mm Diameter, 25 per Package
JTR Press-to-Seal Silicone Isolators confine specimens within a removable hydrophobic barrier. Designed to contain reactants and prevent contamination between specimens. Ideal for isolating cells grown in culture dishes or separate specimens on microscope slides. Silicone Isolators adhere to wet or dry surfaces and remain sealed to smooth surfaces during washing procedures. Easy to apply and remove.
YMC America, Inc Carotenoid grd 5um 10x30mm
YMC Carotenoid is a C30 bonded silica-based reversed phase column that is markedly more hydrophobic than classical C18 phases Even when pure organic eluents are applied many sample solutes are retained The YMC Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules therefore geometric and positional isomers of conjugated double-bonding systems are recognized and resolved It can be used to separate carotenoids in blood samples food products natural product extracts and commercial preparations In addition YMC Carotenoid operates with low aqueous or non-aqueous mobile phases that are desirable in LC/MS and prep fraction recovery
YMC America, Inc Polyam II 120A 5um 10x30mm
YMC-Pack Polyamine II is a silica-based normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases In addition YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes
YMC America, Inc Cell-C guard 20um 10x30mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes
