CA 2587689

A priming unit (31) for a microfluidics device (11) containing a pressurization unit (35) and pressure (46) and temperature detectors as part of a feedback loyg (55) that controls the pressure applied by the pressurization unit (35) an the time during which the pressure is applied. This control feature is particularly useful in controlling the exposure time of the microchannels (15) to dyes in the priming liquids since certain dyes tend to adhere to the walls of the channels and produce non-uniform results.

L'invention porte sur une unité d'amorçage de dispositif microfluidique contenant une unité de pressurisation et des détecteurs de pression et de température faisant partie d'une boucle d'asservissement qui commande la pression appliquée par l'unité de pressurisation et le temps pendant lequel la pression est appliquée. Cette caractéristique de commande est particulièrement utile pour régler le temps d'exposition des microcanaux aux colorants contenus dans les liquides d'amorçage étant donné que certains colorants ont tendance à adhérer aux parois des canaux et à produire des résultats non uniformes.
