Abstract

Dispositif filtrant protégeant la bouche de l'utilisateur d'une pipette. Il a pour but d'empêcher le liquide aspiré dans la pipette ou les bactéries qu'il peut contenir d'atteindre la bouche de l'utilisateur qui exerce une succion: Il comprend un boîtier contenant une membrane filtrante qui le divise en une chambre d'admission et une chambre de sortie. La membrane est hydrophobe et constitue une barrière d'arrêt des bactéries. Un tube souple fixé à un prolongement tubulaire du boîtier est destiné à être monté hermétiquement sur une pipette dans laquelle le liquide doit être aspire. Une embouchure montée sur un autre prolongement tubulaire du boîtier permet d'exercer une succion. Application aux pipettes utilisées en chimie, en biologie et en médecine.Filtering device protecting the mouth of the user of a pipette. Its purpose is to prevent the liquid sucked into the pipette or the bacteria it may contain from reaching the mouth of the user who is sucking: It includes a housing containing a filter membrane which divides it into a chamber of 'admission and an exit chamber. The membrane is hydrophobic and constitutes a barrier to stop bacteria. A flexible tube attached to a tubular extension of the housing is intended to be hermetically mounted on a pipette into which the liquid is to be aspirated. A mouthpiece mounted on another tubular extension of the housing enables suction to be exerted. Application to pipettes used in chemistry, biology and medicine.
