Abstract (en)
The method involves providing a volume of liquid (50), and generating a thermal convection flow at a surface/boundary surface of the volume of liquid by irradiating electromagnetic radiation (30) into the volume of liquid. The volume of liquid is provided in a sample chamber (45) that is designed in an open or closed manner. A capillary having an inner diameter of from 0.05 mm to 0.8 mm is provided as a drop on an object carrier, where the capillary is made from glass. The electromagnetic radiation is produced by an LED or a laser and directed parallel and/or antiparallel to gravitation. An independent claim is also included for a system with a device for executing a method for mixing liquids or particles with liquid.
Abstract (de)
Die Erfindung betrifft allgemein eine Vorrichtung sowie ein Verfahren zum Durchmischen von Flüssigkeiten (50) bzw. Partikeln mit einer Flüssigkeit (50). In einem Flüssigkeitsvolumens (50) wird eine thermische Konvektions-Strömung an zumindest einer Oberfläche des Flüssigkeitsvolumens durch Einstrahlen von IR-Strahlung (30) in das Flüssigkeitsvolumen erzeugt. Dadurch kann eine Verarmungszone an der Oberfläche vermieden werden und Wechselwirkungen der Partikel mit der Oberfläche mittels Oberflächen basierten Messverfahren genauer gemessen werden.
