Device fror parallel and synchronised serial injection of different reagents

摘要

A biological micro-reactor suitable for high throughput screening, is new. <??>The injection system (10) introduces two separate liquids in alternation, into micro-channels. Injection of one liquid forms a mobile reaction chamber. Injection of the other forms a separator. Progress of one liquid is controlled in each micro-channel, at a zone of intervention. A volume for liquid injection is delimited. Control arrests or decelerates a liquid in the microchannel, exploiting a physical or chemical property associated with the liquid. This action has no direct effect on the other liquid. <??>An Independent claim is included for the corresponding method, which forms mobile liquid reaction chambers separated by a second non-miscible liquid. Samples are injected simultaneously into the reaction chambers.
