Silica-gel Bulk
BV silica gels are highly pure microspherical silica gels. The perfectly spherical shape of BV silica gel particles enables higher loading capacity with lower column back pressure while providing good separation. BV silica gels are commonly used in HPLC applications and are available in particle sizes ranging from 1.6 to 300 µm and pore sizes from 60 to 1500 Å. BV proprietary processes produce silica gels with narrow particle size distribution, and the pore sizes are uniform throughout the particles. The broad range of particle and pore sizes of BV silica gels offer many solutions to a variety of needs, including Flash Chromatography, Ultra HPLC, and Size Exclusion Chromatography used in HPLC equipment. BV silica gels wide pore grades and sub 5 µm grades are used to purify or separate large molecules such as polymers, biopolymers, antibodies, oligosaccharides, polysaccharides and proteins.
Chemically bonded silica is also available. BV silica gels can be bonded with C18, C8, C4, Phenyl, NH2, SP, CM, Epoxy, and Diol. We can help you find the best particle combination for your purification/separation needs.
Selection of Silica-gel
Analysis Silica-gel Resin
Products | Particle Size | Pore Size | Surface Area | Carbon Content | pH Value | Application |
C18 | 3/5/10 um | 100Å | 300m2/g | 16% | 2-8 | Can resist 90% water phase, suitable for routine HPLC separation analysis. |
C18H | 5/10 um | 100Å | 300m2/g | 18% | 2-8 | Compared with conventional C18, its bonding amount is larger, the retention is stronger, and the sample load for preparation and separation is larger |
C18L | 5/10 um | 100Å | 300m2/g | 13% | 2-8 | Less bonding than conventional C18, better water resistance |
C18AQ | 5/10 um | 100Å | 300m2/g | 16% | 2-8 | Can resist 100% water phase and has strong retention for some models |
C18BS | 5/10 um | 100Å | 300m2/g | 16% | 1-12 | Ultra deep sealing C18 silica-gel. Small tailing for alkaline samples. Stable performance under strong alkaline conditions. It can also be used for samples prone to dead adsorption. |
