Patent

CA 2477806

A multi-chambered pump-valve device (300) for performing chemical processes, detections or analyses is described herein. The device includes a plurality of chambers having variable volumes in fluid communication with one another via one or more passageways. Liquid may be directed through the device by merely changing the volumes of two or more chambers. Despite the simplicity of the mode for transferring liquids in the device, complex chemical processing sequences may be performed using the device. A plurality of devices may be incorporated into a larger apparatus so that a plurality of chemical processing operations may be performed substantially simultaneously in parallel.

L'invention concerne un dispositif soupape de pompe multi-chambre (300) permettant d'effectuer des procédés chimiques, des détections ou analyses. Le dispositif comprend une pluralité de chambres ayant des volumes variables et en communication fluidique les unes avec les autres par au moins un passage. Le liquide peut être dirigé par le dispositif par la simple modification des volumes d'au moins deux chambres. Malgré la simplicité du mode de transfert de liquides du dispositif, on peut utiliser ce dispositif pour effectuer les séquences de traitement chimique complexes. On peut incorporer une pluralité de dispositifs dans un plus grand appareil pour pourvoir réaliser une pluralité d'opérations de traitement chimique sensiblement simultanément en parallèle.
