METHOD AND DEVICE FOR THE METERED APPLICATION OF A BIOCHEMICAL ANALYTICAL LIQUID TO A TARGET

摘要

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; such a method can be carried out comparatively easily and cost-effectively 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; an appropriate device has a disposable jet element which contains the analytical liquid prepacked by the manufacturer.
