CENTRALIZED BACTERIAL TESTING APPARATUS

PROBLEM TO BE SOLVED: To provide the subject testing apparatus capable of collectively managing bacterial testing, totaling test data, and monitoring and controlling every user apparatuses by connecting the all devices or necessary devices of the user apparatuses, which are used for bacterial tests, to a central processing unit through communication lines. SOLUTION: This centralized bacteria testing apparatus is used for bacterial tests which are carried out as objective tests in sanitary survey and biochemical survey for foods. Each of user apparatuses 11,..., 14 comprises all of or necessary part of a sampling device 4 taking out test samples from testing objects, a crushing device 5 for crushing the test samples, a diluting device 6 for diluting the crushed test samples, a medium preparation device 7 for preparing medium necessary for culturing, a mixing device 8 for adding the test samples into the medium, a culturing device, a bacterial- number counting device 9 for examining the number of bacteria after culturing and a sterilization device 10 for treating the samples after test. Each of the user apparatuses 11,..., 14 has a communication line 3 and a communication lineconnecting unit 2 for connecting to the communication line 3. The user apparatuses 11,..., 14 are connected to a central processing unit through the communication lines 3 and the communication lineconnecting units 2, and thus the centralized bacteria testing apparatus computes the information from each user apparatus.
