Silica gel 60, 0,07-0,2 mm, 250 g, plastic

Silica gel 60 is a chromatographic sorbent with particle size 0,07–0,2 mm, CAS number 7631-86-9 and empirical formula SiO₂. Molar mass is 60,09 g/mol and density ranges from 2,1 to 2,2 g/cm³, supporting reliable bed packing and stable solvent flow in flash and gravity columns. is aimed at laboratories performing normal-phase separations, sample clean-up and preparative fractionation where a medium particle cut reduces back-pressure relative to finer gels while retaining useful surface area. As a member of the silica gel 60 sorbent family, it is widely applied in organic purification, natural-product isolation and method scouting. Manufacturer Carl ROTH supplies this grade for analytical and research chromatography workflows that specify defined particle ranges. Choosing 0,07–0,2 mm helps balance resolution, run time and ease of packing for routine column work. EG number 231-545-4, together with the CAS number, enables consistent substance identification in laboratory inventories, purchasing records and safety documentation for silica-based stationary phases.
