Miles Scientific SILICA GEL W/AGNO3 250UM 20X20CM (25 PLATES/BOX)
These silver nitrate impregnated silica gel plates are for argentation chromatography. They are impregnated with between 5% and 20% silver nitrate which modifies the separation characteristics of the adsorbent layer to permit increased discrimination of certain compounds, particularly those containing carbon-carbon double bonds. They are available with or without a fluorescent indicator. NOTE: The concentration of silver nitrate (5, 10, 15, or 20%) must be specified at the time of order. The most common concentration is 10%.
Sorbent Technologies Inc Purity Flash Cartridges, Granular Silica Gel, Premium Rf, 60A, 40-75um, 4g, 20/pk
Purity™ Flash Cartridges are superior because they are packed with Premium Rf™ Silica Gel. The porosity is 60A, particle distribution is 40-75um, bed mass is 4g, and quantity is 20/pk. Sorbtech's packing technique & Premium Rf's narrow particle distribution results in a uniform packed bed. The benefits are no channeling, higher resolution, decrease in backpressure, faster flow, and faster run time. Additionally, the small pore volume allows for more silica gel per column volume leading to greater loadability and less solvent use. Finally, the high purity silica gel (minimal surface metals) reduces mixed-mode interactions (no peak tailing or resolution loss). The polypropylene cartridge has standard luer-lock end fittings and is spin-welded (leak-free) allowing higher pressures up to 400 psi. The cartridges are compatible with all flash chromatography systems.
