Cosmosil® C18 -PREP Open / Flash Column Chromatography

Nacalai Tesque COSMOSIL 40C18-PREP Packing Material, 40µm, 120Å, 1Kg, 1/Pk

Product Number: 37932-31

Open column chromatography is an excellent and easy technique for large-scale preparation and purification at low cost. COSMOSIL offers both normal and reversed phase packing materials based on totally porous spherical silica, which provides higher separation, less pressure and higher reproducibility than irregular silica.

The large particle size C18 bulk materials are widely used for lab- to process-scale purifications. COSMOSIL offers three different particle sizes of C18 packing materials.

Because reversed phase chromatography employs eluents of high viscosity such as methanol and water, the flow rate is lower than that of normal phase chromatography, which uses solvents of low viscosity such as hexane and ethyl acetate. In general, higher theoretical plate numbers can be obtained with lower flow rates.

• Standard reversed phase packing material for open chromatography
• End-capping treated
• 3 types of particle size (40, 75, 140 µm)
• Special Reagent for specific use - SP (Specially Prepared Reagent)
