They are so small... 390mm 15/20mm ID is not enough for 1g of the substance what you want to purify, maybe 0,1-0,4g. And even the brown glass is not the best.

Get columns like these:


They got an additional refilling "ball" for filling it with a slight excess of eluent, so you got some time between refilling the liquid.
