Manual flash system economic low-tech method for the synthesis laboratory suited for the separation of compounds up to gram levels no expensive equipment required flash manual flash system mn flash chromatography kits include a glass column, eluent reservoir, silica 60 and accessories. These columns are normally filled to a height of about 15 cm, working pressures are 1.5 to 2 bar. The most used adsorbent is silica 60 with particle size 40 – 63 μm , however, you may also use range of polygoprep silica phases. Particle sizes < 25 μm should only be used with very low-viscosity mobile phases, because otherwise flow rates will be very low.
