SYSTEM BASED ON MICROACTUATORS FOR PROGRAMMED AUTOMATION OF SAMPLING AND DISTRIBUTION OF FLUIDS IN VARIABLE MICROVOLUMES

摘要

The invention relates to a system for sampling fluids on a scale of the order of microlitres and up to thousands of microlitres. The system has different automated tasks, including fluid collection and depositing. Said system is characterised in that it includes means for attaching different containers and other elements at the fluid outlets thereof. Moreover, the tasks performed by the invention may be performed at different three-dimensional points. Said tasks can be programmed and are monitored by an active feedback system in order to guarantee correct performance.  The system uses microelectromechanical (MEMS) actuators to generate the required fluid flows, eliminating traditional mechanical components, such as plungers and pistons, as well as the problems associated therewith.   This system comprises a high-precision dedicated sampler that is smaller than those currently available on the market.
