Title
(EN) LIQUID END ASSEMBLY FOR A HANDHELD MULTICHANNEL PIPETTE WITH ADJUSTABLE NOZZLE SPACING
(FR) PIPETTE MULTICANAUX À MAIN ÉQUIPÉE D'UN ENSEMBLE TERMINAL POUR LIQUIDE AVEC ÉCARTEMENT DES BUSES AJUSTABLE
Abstract
(EN)
A handheld multichannel pipette includes multiple fluid-handling nozzles and a rotary adjustment mechanism for adjusting the width of a pattern of nozzles while maintaining equal spacing between pairs of nozzles. Embodiments of the adjustable-spacing multichannel pipette include an adjustable stop mechanism.
(FR)
La présente invention concerne une pipette multicanaux à main comportant de multiples buses de manipulation de fluide et un mécanisme d'ajustement rotatif pour ajuster la largeur d'un motif de buses tout en maintenant un espacement égal entre les paires de buses. Selon l'invention, des modes de réalisation de la pipette multicanaux à écartement ajustable comportent un mécanisme d'arrêt ajustable.
