Abstract: An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

Abstract: A method is provided for preparing a sample of a specimen to be analysed from a thin-layer plate in thin-layer chromatography. The sample is removed from a surface of the thin-layer plate by means of a blade disposed at a receiving opening of a cannula and fed through the cannula to a specimen chamber connected to the cannula. A reduced pressure can be generated in the specimen chamber to suck the sample removed from the thin-layer plate by means of the cannula through the receiving opening into and through the cannula and into the specimen chamber. After removal and feed of the sample, the specimen chamber can be filled with a solvent to dissolve the sample.
