ABSTRACT:
A method or device for integrated dosing and intermixing of small amounts of liquid, has at least one dosing reservoir (3) connected to a reaction reservoir (1) via at least one joining structure (11) and entirely filled with a first liquid. The at least one joining structure (11) is preferably dimensioned such that surface tension of the first liquid prevents the first liquid from penetrating into the reaction reservoir (1) which is entirely filled with a second liquid contacting the first liquid on the joining structure (11). A flow pattern is created in or on the reaction reservoir (1) to thoroughly mix the two liquids.
