I grow a variety of bacteria in identification media in 96 well microtitre
plates in 100 micro litre volumes with no 'edge' effects. I wonder whether
evaporation may be a problem? I use sterile flat bottomed Nunclon plates for
tissue culture. After inoculation I seal the plate with adhesive film (ICN make
a tape on a roll that is the width of a tray. Incidentally, these trays are
used for minimum inhibitory concentration antibiotic assays without a problem.
