ABSTRACT:
A holder of slide test elements for use in an analyzer at a sample-dispensing station, the holder comprising two opposing holding surfaces for holding generally horizontally a slide test element at opposite side edges of the test element, and a tower extending above the holding surfaces for generally centering a dispensing tip above a held slide test element. The holder is improved in that one of the holding surfaces of the holder extends at least sufficiently for underneath a slide test element held by the holding surfaces to be disposed under an approximate center of the held test element, and includes a raised reference surface located under, and disposed for abutting against, an under-surface of the held slide test element, so that a held slide test element is prevented by the raised reference surface from warping downwardly away from a dispensing tip in the tower.
