Apparatus for examining microscopic bodies, more especially for enumerating micro-organisms which have been visualised by the direct fluorescent staining technique which is the subject of British Patent No. 1,503,828, uses a travelling flexible tape of plastics material, such as polyester, to which smears of a sample are applied. The sample is fixed to the tape which is then passed through a sequence of treatment, normally staining, and washing steps, finally dried and presented to a microscope for continuous examination under U.V. excitation. |
