Nacalai Tesque COSMOSIL 140C18-OPN Packing Material, 140µm, 120Å, 500g, 1/Pk
Product Number: 37878-45
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. Reversed phase C18 packing materials are used but restricted to about 30-50% water in the mobile phase.
COSMOSIL C18-OPN is a "Water-Wet" C18 packing material developed for Reversed Phase Open Column Chromatography. The C18-OPN material can be used in 100% aqueous eluents.
