Abstract: A device for generating a liquid film of a liquid medium in a film bag comprising two accumulating surfaces, a braking element, and a running surface are described herein. The device may further comprise a tensioning element. Also provided is an assembly for the controlled exposure of a liquid medium in a film bag using physical radiation and a method for generating a liquid film of a liquid medium in a film bag.

Abstract: A device for generating a liquid film of a liquid medium in a film bag includes two accumulating surfaces spaced apart by an accumulating distance (A), between which the film bag can be arranged and transported along a transport direction; a braking element arranged downstream of the accumulating surfaces in the transport direction, which braking element is arranged to brake the film bag; with a running surface which is convexly curved in the transport direction and is set up and arranged in such a way that the film bag braked by the braking element can be spanned on the running surface behind the braking element. At least a first accumulating surface of the two accumulating surfaces is formed at least in regions by a driven first conveyor belt which is arranged to convey the film bag in the transport direction.

Abstract: Means and methods for dispensing small amounts of liquid from multi-channel microdispensing devices, suitable for use in automatic processing in biological assays and for the cultivation of cells and tissues, by means of optical control of the dosed liquid by specific light barrier units.
