Everest columns have unique selectivity and sensitivity, which are the result of bonding technology that improves C18 surface coverage and deactivates residual silanols. Previously, the 300 Å C18 chemistries had carbon coverage in the 2,8 to 3,6 µmol/m² range. Everest C18 coverage is in excess of 4 µmol/m² and approximates the theoretical limit based on surface area. The increased shielding of the base silica increases column lifetime and reduces the amount of TFA required to shield the silica.

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

Supplier: MICROSOLV

Using proprietary bonding technology, the straight chain C18 hydrocarbon is bonded directly to the TYPE-C silica-hydride surface at two separate points of attachment with direct siliconcarbon bonds. This Si-C bond is virtually indestructible and confers great stability and longevity to these columns.

Supplier: MICROSOLV

Thermo Scientific™ Savant™ SpeedVac™ SPD300P1-230 vacuum concentrator is a large-capacity vacuum concentrator with a modular design, ideal for drying aggressive organic solvents, strong acids, bases, and combinatorial chemistry solvents. It is capable of drying larger quantities of samples at one time and can support high-volume sample preparation needs

Supplier: VARIAN

These rigid, strong ion exchange materials are extremely hydrophilic that is ideal for purification of biomolecules. The PL-SAX and PL-SCX materials are totally polymeric and are chemically and thermally stable over a full range of HPLC conditions.

Supplier: MICROSOLV

Cogent Amide™ has an amide functional group bonded to the silica-hydride surface direct silicon-carbon bonds. Since the ligand is attached to the surface with direct silicon carbon bonds the bonded phase does not hydrolyze in acidic conditions. Also, it does not make a strong association with acetone.

Supplier: Thermo Fisher Scientific

Pierce strong cation exchange and strong anion exchange spin columns use membrane-adsorption as the chromatographic method of choice to fractionate proteins based on their charge differences. The column matrix has a highly porous structure, with pores larger than 3000 nm, giving proteins ready accessibility to the membrane's charged ligands. These adsorptive membranes maintain high efficiencies at high flow rates and during fractionation of large biomolecules with small diffusivities.
