A method and device for storing and dispensing specified subsets from a collection of tens, hundreds or thousands of different reagents to specified locations within microtitre trays or microarr ay substrates (8) or the like. The reagents of interest are stored in racks of syringe-like dispensers (2). These dispensers and /or substrates and/or actuators (5,3) are controllably moved by automated means (11) to a dispensing position where a single action , vibration (7) and weighting system (12) transfers a controlled quantity to a specified location in a microtitre tray or the like. Deficits of the prior art, such as evaporation, cross-contamination, oxidation, waste of reagents and lab-war, and human operator non-reliability are overcome. |
