Abstract: A device for examining and/or treating a sample includes a dispensing unit for dispensing the sample into a sample holder comprising a plurality of wells. Each well has an opening and a base area. The device further includes an optical examining unit, a removal unit for removing the sample from the sample holder and, and a receptacle for moving the sample holder into different work positions within a work region delimited by a respective well. In a respective work position, the optical examining unit, the dispensing unit, and the removal unit are positioned within the work region coaxially on two opposite sides of the sample holder along an optical axis of the optical examining unit. The base area of each respective well is transparent such that an optical capture of the sample is implemented through the base area.

Abstract: A method of production of glass reaction vessels includes irradiating a laser beam of a wavelength for which a first glass plate is transparent onto the surface of the first glass plate. The first hiss plate is etched. Etching of the first glass plate is terminated when the recesses extend, over only a portion of the thickness of the first glass plate and therefore the recesses have a bottom formed in the first glass plate as a single piece.

Abstract: A device for depositing liquid droplets onto a carrier includes a droplet generator and a holding device for the carrier, and a detector arranged to detect a signal for each liquid section or droplet, and a transport device for moving the holding device relative to the droplet generator and preferably a memory connected to the detector.

Abstract: The invention relates to a method for producing reaction vessels from glass and to the glass reaction vessels obtainable by this method. The method comprises the following steps: 1. irradiating the surface of a first glass sheet by means of a laser beam of a wavelength for which the first glass sheet is permeable, 2. etching the first glass sheet to form recesses that extend over the complete thickness of the first glass sheet, and 3. connecting a second sheet with a surface of the first glass plate.
