I think free standing instruments that let you do things without or with another computer are what will sell today.
I like micropython for low cost programmable systems.  My electroporator can take a slow (1 MHz) sampling rate oscillograph
of a 1 to 8 millseconds long pulse of HV and the current through the test cuvette.  And then a full UI
host computer can be used via USB and a python program running on the host to get data files.  Then a script or button can run 
them through octave, gnuplot, etc.

The culture shock instrument will have a small OLED display with
that oscillograph and some data in text on it also.  It will be a free standing instrument for shocking samples and
tagging them with three character alphanumeric label codes to write on vials...and later
some of the detailed data in files on the culture shock can be associated with the vials.
