Silica Gel for Column Chromatography
Nacalai Tesque Silica Gel 120, (Spherical), 70-230 mesh, 120Å, 1Kg, 1/Pk
Product Number: 30734-41
Since conventional silica gels are weakly acidic, some pH sensitive compounds may be decomposed during the purification by column chromatography with the acidic silica gels. The pH of Silica Gel 60 (spherical neutral) is adjusted to nearly neutral for the separation of not only pH sensitive compounds but also new compounds that the physical properties are still unknown.
- The pH of silica gel is adjusted to neutral
- Suitable for the separation of pH-sensitive compounds
- Special Reagent for specific use - SP (Specially Prepared Reagent)
