Abstract
Abstract Apparatus for carrying out a liquid reaction characterised by a first slidably mounted stage (11) adapted to carry a sample cell or cells (80); a second slidably mounted stage (13) adapted to carry a reagent cell or cells (18); pipetting means (53,54) for sucking a reagent from a reagent cell (18) and discharging it into a sample cell (80); means (38,40) for sliding the first and second stages (11,13) horizontally to and from positions in which a sample cell (80) and a reagent cell (18) are respectively in vertical alignment with the pipetting means (53,54); and means (49,50,52) for effecting vertical sliding movement of the pipetting means (53,54) into and out of a position or positions in which reagent may be sucked from a reagent cell (18) and discharged into a sample cell (80).
