Abstract: An improved cell culture plate for in vitro cultivation of cells and/or tissue cultures, the cell culture plate comprising a base member and a flat removable lid, the base having the external dimensions of a standard cell culture plate and further having multiple sets of open-topped wells. Each set of wells comprises two or more wells of increasing area and volume, and the collection of sets are preferably arranged in side-by-side columns, each column being adapted for use in cell or tissue culture expansion. The sizing and configuration of the wells enables cell culture expansion through the use of a single cell culture plate, rather than through use of a series of plates having wells of increasing size and volume.

Abstract: A microprocessor based apparatus and method for recording antimicrobic susceptibility data and biotype data. Manual data entry means in the form of two separate arrays of switches are provided for entering susceptibility data from microdilution test panels and a biochemical identification panels. An LED array is provided in a test panel housing on the front panel of the instrument cabinet in which the system is housed for feedback of data entry under microprocessor control. A microprocessor system records the entered well coordinated data for the microdilution test panel wells and the biochemical identification panel wells and converts the entered data into a printout of the minimum inhibitory concentration (MIC) of antimicrobics in the MIC test panel and a probable identification of the unknown microorganism. A multicopy form is provided for the printout from a printer functioning under microprocessor control.
