Product Description

Product Name  Silica gel 60


Product Description  Silica Gel is used to help remove polar impurities and colors, oftentimes in Color Remediation Columns. Silica gel is made from silicon dioxide that has an absorptive texture like pellets. Silica gel is super absorbent and naturally acidic, so it can absorb material that needs to be separated in the extraction and filtration process.
Average pore diameter: 50-75A, Pore volume: 0.5-0.7 m/g, Surface area: 450-600m2 /g
Formula  SiO2. n (H2O)  (amorphous silicon dioxide)
CAS No.  7631-86-9 (silica)
Applications: Silica gel is used in normal phase column chromatography without applied pressure (gravity pulled). It is used as an adsorbent in various applications and in removing impurities. It is used as stationary base in column chromatography.
