Abstract

A microfluidic arrangement for extracting and optionally processing an extract from a sample and for transferring the extract in flowable form to a microfluidic chip using an extractor with a compressible extraction chamber and at least one opening thereof, a reactor that has a reaction chamber, an inlet opening that communicates with the at least one opening of the extractor, wherein the two openings define a flow path between the chambers, an outlet opening for fluidically connecting to the microfluidic chip and a ventilation opening of the reaction chamber, and having a filter arrangement installed in the flow path between the extractor and the reactor. A lab-on-a-chip system with such a microfluidic arrangement and a microfluidic chip that is rigidly connected to the reactor.
