21- & 22- and 42-&44-Well Mutichannel-compatible Combs for Owl A2

thingiverse

These are combs for the Owl Scientific A2 large horizontal agarose gel electrophoresis system. There are design files available for a 21 well x 1.5 mm and a 22 well x 1.5 mm comb, as well as a 42 well x 1.5 mm and a 44 well x 1.5 mm comb. The wells are carefully spaced to accommodate loading with an 8- or 12-well multichannel pipet. The 42 and 44-well combs are spaced so that the tips will load every other lane. I have not tested the 42 or 44 well combs, so I would appreciate feedback from anyone who has tried them if they work. Unfortunately this gel is not wide enough for 25 wells across (2 x 24 + a marker), but 21 or 22 can be better than nothing if you happen to have this system. Design files in Autodesk Inventor (2021) part format as well as STL files are included.
