Abstract
A microtitration unit being at least one container of transparent material for accommodating biological test reaction mixtures. The container is subdivided into at least two chambers suitable for accommodating different test reaction mixtures by at least one partition which extends from the inside of the bottom of the container and which is of lower height than the internal height of the container.
Claims1
A method for testing and analyzing a biological test fluid comprising
- introducing into at least two chambers of a microtitration unit, different test reaction mixtures, comprising agar-agar nutrient medium, test microorganisms and a microbial growth indicator, said microtitration unit having at least one container of transparent material, the container including an opening for the introduction of test reaction mixtures and biological test fluid and at least one partition subdividing the container into said at least two chambers for accommodating said biological test reaction mixtures, the at least one partition extending from the inside of the container bottom and being of lower height than the internal height of the container and above the filling levels of the different test reaction mixtures,
- adding a sufficient amount of biological test fluid to be tested or analyzed whereby the biological test fluid flows over the top edge of the at least one partition whereby the biological test fluid floods over the at least two chambers and the biological test fluid makes contact with the different test reaction mixtures, and
- detecting the results of the interactions of the biological test fluid with the different test reaction mixtures.
