Multi-chamber impedance measuring module-cap combination

Claim 1

A MULTI-CHAMBER MODULE-CAP COMBINATION ULSFUL FOR OEASURING THE IMPEDANCE OF SAMPLES OG NITRIENT MEDIA IN THE CHAMBERS THEREOF, SOME OF WHICH SAMPLES INCLUDE AEROBIC MICROORGANISM THEREIN, COMPRISING, IN COMBINAION: A STIFF, FLAT, ELECTRICALLY NON-CONDUCTIVE BOARD; A PLURLITY OF IDENTICAL HOLLOW CYLINDERS OPEN AT BOTH ENDS, EACH OF SAID CYLINDERS SEALED AT ONE END THEREOF AT ONE SIDE OF SAID BOARD TO FORMA CHAMBER, EACH CYLINDER EXTENDING TO GENERALLY THE SAME HEIGHT FROM SAID ONE SIDE OF SAID BOARD; A PLURLITY OF ELECTRICALLY CONDUCTIVE STRIPS ATTACHED TO SAID ONE SIDE OF SAID BOARD, SAID STRIPS PROVIDING A PAIR OF SPACED-APART CONTACTS UNDER EACH OF SAID CHAMBERS FOR MEASURING THE IMPEDANCE FROM ONE OF SAID CONTACTS TO THE OTHER OF A SAMPLE OF A NUTRIENT MEDIUMTHEREWITHIN, SAID STRIPS FURTHER PROVIDING ACCESSABLE PORTIONS THEREOF FOR CONNECTION TO IMPEDANCE-MEASURING CIRCUITRY; AND A PLURALITY OF CAPS MADE OF A RESILIENT MATERIAL ADAPTED TO FIT OVER SAID CYLINDERS, EACH CAP COMPRISING A GENERALLY FLAT DISC-LIKE TOP, THE DIAMETER OF SAID TOP BEING GREATER THAN THE OUTER DIAMETER OF SAID CYLINDER, AND A SKIRT PROCEEDING AWAY FROM SAID TOP GENERALLY PERPENDICULARLY THERETO CIRCUMFERENTIALLY THEREOF, THE LENGTH OF SAID SKIRT BEING GREATER THAN THE HEIGHT OF SAID CYLINDER SO THAT WHEN SAID CAP IS FITTED OVER SAID CYLINDER SAID TOP IS PREVENTED FROM SEALING AGAINST THE OTHER END OF SAID CYLINDER AND SAID SKIRT EXTENDS AGAINST SAID ONE SIDE OF SAID BOARD TO PREVENT CONTAMINATION OF SAID CHAMBER, SAID SKIRT INCLUDING INTERNALLY THEREOF A PLURALITY OF RIBS UPRAISED THEREFROM GENERALLY EVENLY SPACED FROM ONE ANOTHER LONGITUDINALLY THEREOF, THE INTERNAL DIAMETER OF SAID SKIRT BEING SLIGHTLY GREATER THAN THE EXTERNAL DIAMETER OF SAID CYLINDER AND AN INTERNAL DIAMETER DEFINED BY THE TOPS OF SAID RIBS BEING SLIGHTLY LESS THAN THE EXTERNAL DIAMETER OF SAID CYLINDER, WHEREBY WHEN SAID CAP IS IN PLACE OVER SAID CYLINDER A PRESS FIT RESULTS BETWEEN SAID RIBS AND SAID CYLINDER AND A GAS FLOW CHANNEL IS PROVIDED FROM THE INTERIOR OF SAID CHAMBER TO THE SURROUNDING ATMOSPHERE, AS DEFINED BY THE SPACE BETWEEN SAID CYLINDER, SAID SKIRT AND SAID RIBS AND MEANS FOR PREVENTING THE BOTTOM OF SAID SKIRT FROM FORING A GAS-TIGHT SEAL WITH SAID ONE SIDE OF SAID BOARD.
