ABSTRACT:
An instrument for chemical and microbiological tests comprises a sample container for temporarily storing a liquid sample; a plurality of sample-holding portions formed on the bottom face of the sample container; and a liquid-absorbent body capable of coming in contact with the liquid sample so that the body can absorb the excess sample, when the liquid sample is introduced into the container, while retaining the sample to be held on the sample-holding portions. This instrument can be used in a chemical or microbiological test wherein a sample is used in a relatively small amount and, in particular, those requiring a large number of reactions and cultivation. Moreover, the instrument does not require the dispensation of a sample to each reaction system and does not cause any scatter of the sample in the surroundings.
