Patent ID: 8062904

Claim:
A method for the integrated metering and mixing of small quantities of liquid, comprising the steps of: completely filling at least one metering reservoir ( 3 , 103 , 203 , 223 , 303 ) that is in communication with a reaction reservoir ( 1 , 101 , 201 , 301 ) via at least one connection structure ( 11 , 111 , 211 , 212 , 311 ) with a first liquid, wherein said at least one connection structure is dimensioned such that the surface tension of the first liquid prevents an entry into the reaction reservoir ( 1 , 101 , 201 , 301 ); completely filling said reaction reservoir ( 1 , 101 , 201 , 301 ) with a second liquid whereby the second liquid comes into communication with the first liquid at said at least one connection structure ( 11 , 111 , 211 , 212 , 311 ); and producing a flow pattern at least in or on said reaction reservoir ( 1 , 101 , 201 , 301 ) using a sound wave generation device that causes the mixing of the first and second liquids.
