Packing Materials for Column Chromatography
Nacalai Tesque COSMOSIL 40C18-PREP C18 Packing Material, 40 um, 500g
Product Number: 37932-15
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.
