UniSil® 30-300 C4 utilizes advanced surface bonding and end-capping technology, providing excellent chemical stability. After 5 years of storage at room temperature, re-testing of multiple batches of the resin shows no significant changes in quality control results compared to the initial analysis.
Compared to similar products on the market, UniSil® 30-300 C4 offers the following unique advantages:
• Monodisperse silica resin with extremely narrow particle size distribution, CV ≤ 5%;
• Precisely controlled pore size and distribution, effective specific surface area, and pore volume for high loading capacity;
• Unique end-capping technology effectively modulates residual silanol groups on the silica surface to meet diverse application needs;
• Excellent chemical stability, suitable for separation and purification at pH 2~8.
