NEUROSYIL C18 Preparative Column 300 Å
It’s a reversed-phase HPLC column, with a C18 (octadecyl) bonded silica stationary phase — a very common “workhorse” for reversed-phase chromatography.
The “300 Å” refers to the pore size of the silica packing material. Compared to conventional C18 columns (often 100–120 Å), 300 Å is a wide-pore packing.
It is offered in preparative (or semi-preparative) format, meaning it’s intended for purification / isolation on a scale larger than typical analytical HPLC.
