Abstract

L'invention concerne un dispositif automatique de prélèvement par pipette présentant un bras de prélèvement par pipette et un dispositif de détection pour déterminer une force exercée (détecteur d'impact) sur la pointe d'une aiguille de prélèvement par pipette. L'invention vise à mettre au point un détecteur d'impact fiable présentant une bonne sensibilité, qui permette de remplacer aisément une aiguille de prélèvement par pipette. A cet effet, il est prévu que le bras de prélèvement par pipette se compose d'au moins quatre corps partiels (base de bras de prélèvement par pipette, embout de bras de prélèvement par pipette, partie inférieure de bras de prélèvement par pipette et partie supérieure de bras de prélèvement par pipette) interconnectés par des assemblages de type articulé. La partie inférieure du bras de prélèvement par pipette et la partie supérieure du bras de prélèvement par pipette sont disposées l'une sur l'autre et sont placées entre la base du bras de prélèvement par pipette par l'intermédiaire de laquelle le bras de prélèvement par pipette peut être mis en place sur un dispositif de déplacement et l'embout du bras de prélèvement par pipette sur lequel l'aiguille de prélèvement par pipette peut être placée. A cet effet, les assemblages de type articulé sont conçues de sorte qu'une force mécanique agissant à l'encontre de l'extrémité libre de l'aiguille de prélèvement par pipette et le long de l'axe longitudinal de l'aiguille de prélèvement par pipette induise un déplacement vers le haut de l'embout de bras de prélèvement par pipette vis-à-vis de la base du bras de prélèvement par pipette. Le dispositif de détection peut déterminer un tel déplacement vers le haut de l'embout de bras de prélèvement par pipette vis-à-vis de la base du bras de prélèvement par pipette et le convertir en signal.
