Bacterial contamination monitor
Abstract
Abstract A PORTABLE TESTING INSTRUMENT FOR DETERMINING THE LEVEL OF BACTERIA AND OTHER MICROBIAL (AGAL, PROTOZOAL, ETC.) CONTAMINATION WITHIN A MONITORED SAMPLE WITHOUT THE NEED FOR EXTERNAL ELECTRIC RECORDING DEVICES OR EXTERNAL POWER SOURCE. THE INVENTION UTILIZES AN ADENOSINE TRI-PHOSPHATE (ATP) LIGHT REACTION, THE INTENSITY OF WHICH IS DIRECTLY PROPORTIONAL TO THE PRESENCE OF THE ATP. HIGH-SPEED FILM IS USED FOR TIME DISPLAYING THE LOW LEVEL OF BIOCHEMICAL LIGHT PRODUCED, THE LIGHT EXPOSURE INTENSITY BEING COMPARED TO A CALIBRATED SCALE FOR DETERMINATION OF THE BACTERIA CONTAMINATED LEVEL. ADDITIONALLY, THE INSTRUMENT INCORPORATES A NOVEL DISPOSABLE PACKAGING CONCEPT FOR STORING AND PRODUCING THE BIOCHEMICAL REACTION.
