procedure and apparatus for the detection and avkenning of pipetteringspositioner in a pipetteringssekvens which manually genomfores at a testplatta with a matrix of peel

摘要

A method and an apparatus for indicating and sensing pipetting positions in a pipetting sequence which is manually performed at a transparent conventional microtest plate is distinguished substantially thereby that a program control means (600) is brought to activate, in accordance with a previously programmed pipetting sequence, an illumination means (200;14) which distinguishingly illuminates the rim (115) of a test plate well (114) at which a manual pipetting operation in the sequence shall be carried out, in that the position of a pipette is sensed by means of sensing means (300) at the insertion of the pipette into a well (114) and in that the sensed pipette position is compared to the position for the well (114) indicated by the illumination means (200), and in that the comparison is carried out by means of a comparison means which, if the compared positions coincide, is brought to emit a signal to the control device (600) for initiation of the next sequence step, or, if the compared positions do not coincide, is brought to emit an alarm signal.
