Abstract: A temperature regulating container handles multiple samples which can be optically measured in real time while regulating the temperature of the samples. The samples can be moved at high speed by, for example, shaking without requiring a complicated mechanism. A cell culture container is a combination of three kinds of members: a temperature regulating liquid-holding member, a sample-holding member, and a lid. The cell culture container ensures that multiple samples are contacted with a temperature regulating liquid so that the temperature of the samples can be maintained at a uniform temperature, or quickly increased. The lid contacts the surface of the samples, preventing the samples from drying and contamination and, preventing dew formation on an optical path for performing optical measurement. The distance the light passes through the samples can be held constant to thereby assure accurate optical measurement; and sample containers can be easily moved.

Abstract: Provided is a test apparatus in which a test for bacterial identification or antimicrobial susceptibility can be promptly determined. A division state of bacteria is monitored by performing microscopic observation of shapes and the number of the bacteria in each of wells in a culture plate for bacterial identification culture or an antimicrobial susceptibility test, and it is determined whether or not the bacteria grow in a stage shifted from an induction phase to a logarithmic phase, with reference to an image obtained through microscopic observation. In addition, determination performed based on turbidity in the related art may be combined with determination performed based on microscopic observation in which change and the like in the shapes of the bacteria are monitored. Accordingly, it is possible to realize a highly accurate test result.
