The monitoring instrument comprises a casing 10 having a section 14 which can be pivoted between one position generally flush with a top face of the casing, and a second position which is generally vertical. The pivoted section 14 includes an elongate sample chamber 15 to receive a sample. The instrument has a light detector arrangement for sensing light emitted from a sample inserted into the sample chamber, to provide a measure of the light emitted in a predetermined time period. The instrument is used for monitoring bio-luminescent light emission, in which a swab, pre-moistened with breakage reagent, is wiped over a surface to be tested, then contacted with enzyme solution so that light will be emitted from the swab sample if it has picked up cells: the swab is then inserted into a transparent tube which is placed in the sample chamber 15. <IMAGE> |
