MICROBIOLOGICAL TESTING APPARATUS

An improved microbiological test tray (10, 64, 80 ) is described which is provided with fasteners (28, 30; 52; 98, 100) so that two or more of the trays may be joined together for ease in inoculation, incubation, lyophilization and reading. In another aspect of the invention an improved tray structu...

Beschreibung
Zusammenfassung:	An improved microbiological test tray (10, 64, 80 ) is described which is provided with fasteners (28, 30; 52; 98, 100) so that two or more of the trays may be joined together for ease in inoculation, incubation, lyophilization and reading. In another aspect of the invention an improved tray structure is described which allows trays to be stacked and which provides openings (?6, 96) for the flow of vapour during the lyophilization stage so that a greater number of trays may be lyophilized at the same time and also that lyophilization may be carried out in a shorter period of time due to the improved vapour flow.
