The original design image sent to Finkenbeiner for the Kirkup-style chemostat, modified from the design originally created by D. Dykhuizen. Finkenbeiner modified it further when creating it in borosilicate and quartz, by moving the tubing off the barrel (more like the original Dykhuizen design) and adding struts to it; and subsequent iterations off-set the gas output lines at an angle downwards to ease tubing attachment.
