Here is a pic of What I speak of. Along with a concrete slab/ bolts/ motor/ pulley/ steel rod/ and two support arms with pillow block bearings with the 3" long 1" pipe running through each side into a bearing you have a shaking hydrogenator like the one in vogel. Or with an extended gas dispersion tube an aerobic culture flask or just the bottle without shaker a gassing chamber. It has many uses.
Yes, That pic really is me!
