Method and Device for Dosing and Mixing Small Amounts of Liquid

A device for the integrated metering and mixing of small quantities of liquid comprising

• a first reservoir (3, 103, 203) for a first quantity of liquid (123);
• a second reservoir (1, 101, 201) for a second quantity of liquid (121);
• filling passage structures (7, 11) which are in communication with a reservoir at one respective end and with a filling device (17, 19) at the other respective end;
• at least one connection passage structure (5, 6, 105, 227) which connects the two reservoirs and has a cross-section at least in one region in the direction of view of the connection line of the reservoirs which is smaller than the cross-sections of the reservoirs;
• at least one device for the generation of a laminar flow along the at least one connection passage structure (5, 6, 105, 227);
• and
• at least one device (15, 215) for the mixing of the quantities of liquid in or on the second reservoir (1, 101, 201).
