The present invention provides apparatus and methods for collecting a plurality of measured quantities of a powdered material and dispensing each of the measured quantities to, for example, a multi-well vessel. Vacuum is used to collect the powdered material and at least one of gravity, a gas push, or a physical push is used to dispense the powdered material. Apparatus and methods of the invention are particularly useful for collection and delivery of powdered materials in high throughput chemical synthesis and biological assay environments where accurate measurement and dispensing of powders is critical.
L'invention concerne un appareil et des procédés permettant de prélever plusieurs quantités mesurées d'un matériau pulvérulent et de distribuer chacune de ces quantités vers un récipient multipuits, par exemple. On utilise le vide pour prélever le matériau pulvérulent et au moins une sollicitation gravitaire, gazeuse ou physique pour distribuer ledit matériau pulvérulent. Cet appareil et ces procédés sont particulièrement utiles en matière de prélèvement et de livraison de matériaux pulvérulents en synthèse chimique à haut rendement et dans des milieux de dosage biologique où des mesures et la distribution précises des poudres sont indispensables.
