Title: Procedes et dispositif de transfert de liquides sans contact et utilisations
Inventor: SINGH TARLOCHAN
IPC: B01L3/02
Filed: 2001-12-12
Abstract: Cette invention concerne des procédés faisant intervenir des ondes acoustiques pour le transfert sans contact de petites volumes. On fait se propager des ondes acoustiques dans un réservoir distinct de liquide source de manière à provoquer l'éjection d'une micro-gouttelette unique à partir de la surface du réservoir. La gouttelette est éjectée vers une cible avec une force suffisante pour faire pénétrer cette gouttelette avec la cible. En l'absence de contact entre le liquide et un quelconque dispositif de transfert tel qu'une pipette, les risques de contamination sont réduits au minimum. Ces procédés peuvent s'utiliser pour transférer des liquides d'un ensemble de sites sources à un ensemble de sites cibles et rendent possible une automatisation de précision pour les techniques les plus diverses, criblage y compris, et pour des méthodes de synthèse couramment utilisées dans le domaine des biotechnologies.
