ABSTRACT:
A method for the metered application of a biochemical analytical liquid to a target, wherein the liquid is ejected in small quantities on to the target through a jet from a jet chamber by a procedure in which a partial volume of the liquid in the jet chamber is evaporated and expanded for a short time whenever a quantity of the liquid is to be ejected. The invention further relates to a device with a disposable jet element which contains prepackaged analytical liquid.
