Title (DE) DOSIERVORRICHTUNG MIT RADIALER ANORDNUNG VON VENTILEN
(EN) METERING DEVICE WITH RADIALLY ARRANGED VALVES
(FR) DISPOSITIF DE DOSAGE AVEC AGENCEMENT RADIAL DES VANNES
Abstract:
(DE) Offenbart wird eine Dosiervorrichtung bei der die Ventile auf einem ringförmigen Träger angeordnet sind. Die Multifunktions-Dosiervorrichtung findet Verwendung als Fraktionskollektor, Probenaufgeber oder Dosiervorrichtung in einem Sequenziergerät zur Analyse von Proteinen und Peptiden. Aufgrund der besonderen geometrischen Anordnung der pneumatisch steuerbaren Ventile können kurze Leitungen zu den Reaktionsgefäßen eingehalten werden, was beim Arbeiten im Mikromaßstab besonders vorteilhaft ist.
(EN) Disclosed is a multi-function metering device in which the valves are disposed round an annular support. This device can be used as a fraction collector, sample dispenser or metering device in sequential-analysis equipment for the analysis of proteins and peptides. Owing to the particular geometrical disposition of the pneumatically operated valves, the lines to the reaction vessels can be kept short, which is particularly useful in equipment used for micro-scale work.
(FR) L'invention concerne un dispositif de dosage dont les vannes sont disposées sur un support annulaire. Ce dispositif de dosage à fonctions multiples est utilisé comme collecteur de fractions, distributeur d'échantillons ou dispositif de dosage dans un dispositif séquenciel d'analyse de protéines et de peptides. La disposition géométrique particulière des vannes à commande pneumatique permet d'avoir des conduites courtes menant aux récipients de réaction, ce qui est particulièrement avantageux lors de travaux à l'échelle micrométrique.
