Ethanol ≥99.9% (by GC), LiChrosolv®, gradient grade for liquid chromatography, Supelco®

Supplier: MilliporeSigma

Offering a high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. Since separations are normally carried out under gradient conditions in analytical HPLC, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.

XK Columns, Cytiva

Supplier: Cytiva

XK empty columns are designed for liquid chromatography at low to medium pressure. The user friendly design ensures trouble-free operation with fittings for direct connection to high performance liquid chromatography systems. They are compatible with aqueous solutions and most organic solvents used in liquid chromatography of macromolecules. They are not resistant to acetone, ketones, chlorinated hydrocarbons, aliphatic esters and phenol. Should be avoided: >10% NaOH, >10% HCl, >5% acetic acid and strong mineral acids.

C Columns, Empty Chromatography Columns, Cytiva

Supplier: Cytiva

C-series columns are designed for standard chromatography. The column hardware consists of borosilicate glass, PA, fuororubber, PP, superpolyoxymethylene and silicon rubber. The eluent inlet pieces incorporate a 'reverse funnel' design that distributes eluent evenly over the cross-sectional area of the gel bed surface. This causes minimal disturbance of the gel bed and results in improved flow properties. These columns are resistant to aqueous solutions and solvents used in liquid chromatography. They are not resistant to acetone, ketones, chlorinated hydrocarbons, aliphatic esters, phenol, NaOH, >10% HCl, >5% acetic acid, or strong mineral acid.
