The biologists employ the use of a spectrometer to measure how many cells are in solution.

=Prep= The device works off a control to measure all other samples. In my experiments the control has been an empty solution.
 * YPD for yeast culture
 * 1% SDS with 2-ME (mercaptoethanol) when working with the lyticase

=The program=
 * 1) Press any key to begin
 * 2) load samples with "window" of sample chamber aligned with hole in holder
 * 3) set program and number of samples
 * 4) run experiment
 * 5) collect data

=Results= I've yet to figure out the nomenclature of the setup. To me we just get some unitless number (perhaps this is true) and we ultimately want a smaller (or sometimes greater) number. Then we use that number and manipulate it to get the concentration of "particles" that we want.
