The interconversion of machine settings and size determinations between seven models of Coulter counter as illustrated by values for human spermatozoa.
Calibration of the Coulter counter Models ZB Industrial, B Industrial D and D Industrial using 21 standard particles is reported using the same method as previously described for the Models B Medical, F and A. All the machines showed significant differences in design and sensitivity. The additional data allowed the relationship between the machine constant and the aperture diameter to be calculated and volume factors were calculated for each combination of settings on each machine. The general method of interconverting size data and machine settings between the instruments was demonstrated using human spermatozoa as an example.
