High performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Cogent Bidentate C18™ HPLC Columns are manufactured with TYPE-C™ silica (silica hydride) and a straight chain C18 hydrocarbon bonded directly to the Silica Hydride surface with two separate points of attachment. The manufacturing of the Silica makes these columns virtually indestructible.
Flexible Multiport System for DURAN® GLS 80 Wide Mouth Bottles. The multi-port system consists of a GLS 80® screw cap with four ports. The tubes are fed through these ports and secured with inserts and screw connections. There is a choice of 5 inserts, each with different internal diameter depending on the application. Unused ports can be fitted with a blanking cap, if necessary. Sterile pressure compensation can be achieved…
GL 45 Screw caps with two or three ports. The connection system for DURAN® laboratory bottles are screw caps with GL 45 threads and two or three ports. Liquids can be added to or removed from bottles using the tube connections. Using a universal GL 14 tube adapter and different inserts, four different tube diameters can be used.This flexible, modular system provides the option of combining various components according to need…
DG safety caps are high-grade, flexible connection systems which have been designed specially for handling aggressive, gas-forming liquids. Available with 1, 2 or 3 connection ports with optional stopcocks, DG safety caps are particularly suitable for pharmaceutical and chemical applications. The safety caps come complete with v-ring seal (inside diameter 3.2 mm) and are ready for immediate use. V-ring seals are optionally ava…
The pentafluorophenylpropyl (PFP) stationary phase of Ascentis® Express F5 provides a stable, reversed-phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming p-p and mildly steric interactions, F5 phases also retain compounds by polar interactions. As a result of having both polar and non-polar character, F5 phases can show dual-mode retention behavior, some…
