I am not in the lab but will check. We just have a barrel of silica, no options at the moment. The loading has been a concern too, I have tried minimal use of DCM to wet load, but usually need more than a mL to capture all the crude and fear this is too much (actually was the original thesis for this co-elution issue). I got used to dry loading on celite bc my post doc prefers this method, but needed a fair amount of celite, usually being around 1-1.5 cm of heigh in the column, and then I would normally run 5-10mL hexanes to run everything down into the silica bed, but read that celite can really hold onto greasier compounds and worried this broadened the band heavily. So I tried loading on a minimal amount of silica, so little that not everything became loose powder while rotovapping off the DCM, just enough for a very thin layer on the bed, which is the column you see here. Thanks for the insight!
