Cosmosil® SL-II-PREP Open / Flash Column Chromatography
Nacalai Tesque COSMOSIL 75SL-II-PREP Packing Material, 75µm, 120Å, 5Kg, 1/Pk
Product Number: 38012-06
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.
- Standard packing materials for normal phase chromatography
- Ultra pure silica gel packing material more than 99.99% purity
- Special Reagent for specific use - SP (Specially Prepared Reagent)
