Abstract: In a method for executing a chemical workflow, the workflow is processed step-by-step manually and/or in an automated manner. While it is being processed, the workflow is recorded by means of a recording device and the recording so created is by means of a computer evaluated and converted into instructions which comprise detailed working instructions for a laboratory worker or for at least one automated laboratory device, on the basis of which working instructions the recorded workflow can be repeated manually and/or in an automated manner or, based thereon, a modified workflow can be created.

Abstract: In a method for the production and/or treatment of a three-dimensional object with a printing material which is dispensed at a target position in the form of discrete three-dimensional printing material elements, a metering device is moved to at least one reservoir in which a supply of printing material is kept and, by means of the metering device, printing material is picked up from that at least one reservoir. The metering device is transported to a target position defined in all three spatial dimensions and, at that target position, a metered quantity of printing material is applied to a substrate or to a three-dimensional object arranged thereon or being constructed thereon, in order to create a printing material element. The creation of a printing material element is repeated until the three-dimensional object has been fully constructed and/or treated.

Abstract: In a method for logging and analysing a scientific experimental workflow, over the course of the workflow a video recording, which includes a multiplicity of successive individual images, of at least parts of a workspace in which the workflow is being executed and, at the same time, values of parameters relevant to the workflow are recorded and stored as separate data sets in a digital data bank. The data sets contain the individual images of the video recording and the values of the parameters over time assigned to a common reference time, so that at each timepoint there is a clear temporal association between the individual images of the video recording and the values of the parameters. The data sets of the parameters are stored in a searchable form, so that it is possible to search for parameter events at which a parameter exhibits a searched value or a searched change.

Abstract: A device for producing a film-shaped test body from a solidifiable test substance includes a substrate on which a substance film is formed from test substance applied to the substrate. The device further includes a film-detachment tool having an adhesive surface with which the tool can be placed on the substance film formed on the substrate, the film-detachment tool being shaped so that it leaves a sub-region of the substance film uncovered. The adhesive surface of the film-detachment tool preferably exhibits greater adhesiveness towards a test film that can be created by solidification of the substance film than does the substrate.

Abstract: In a spraying process for coating a substrate with a substance atomised in a stream of gas, a spray head is used to generate a stream of gas that acts upon the substrate. The substance is present in a syringe-like application container equipped with an application tip. The application tip of the application container containing the substance is introduced into the stream of gas outside the spray head at a distance therefrom and transversely with respect to the main direction of flow of the stream of gas, and the substance is introduced from the application container into the stream of gas at that location.

Abstract: A metering apparatus including a scale on which a metering head is disposed in such a manner that the scale measures the weight of the metering head, and a metering tool for taking up and dispensing substance, attached to the metering head. The metering tool is configured as a glass tubule having a glass punch slidably disposed therein, forming a seal. The metering head is provided with a first gripping tool for clamping the glass tubule in place and with a second gripping tool for clamping the glass punch in place. The metering head furthermore has a raising and lowering device for raising and lowering the second gripping tool relative to the first gripping tool, such that the glass punch can be raised and lowered in the glass tubule of the metering tool.

Abstract: In a method and a corresponding device for producing an extrudate, starting products are introduced into an extrusion container, heated, and homogeneously intermixed by dual asymmetric centrifugation of the extrusion container. The extrusion container is rotated about a primary rotation axis that extends outside the extrusion container, and is simultaneously rotated about a secondary rotation axis that extends through the extrusion container and is situated at an acute angle with respect to the primary rotation axis. Lastly, the intermixed starting products are jointly extruded from the extrusion container. The method and the corresponding device are particularly suitable for processing small and very small substance quantities.

Abstract: An apparatus for metering a substance into a target container includes a gripping tool, with which a metering tool can be picked up and released, and a scales. The metering tool is configured as an adhesive body which is wetted by a substance so that a small amount of substance measurable by the scales remains adhering to the metering tool. Once the desired amount of substance has been picked up with the metering tool, the latter, including the substance adhering thereto, is released into the target container. A controller controls the scales and the gripping tool and decides whether the amount of substance picked up by the metering tool is usable or whether more substance should be picked up or whether the metering tool should be discarded and somewhat less substance picked up with a fresh metering tool.

Abstract: A container for taking up and dispensing a substance includes a glass tubule, a glass punch that slides adjustably in the glass tubule, forming a seal, and a glass sleeve closed on one side, in which the glass tubule is accommodated. The glass sleeve is shorter than the glass tubule, so that the glass tubule projects out of the glass sleeve. The glass punch is longer than the glass tubule and projects out of the glass tubule at the end situated outside of the glass sleeve. The glass punch does not fill the glass tubule completely, so that a substance chamber remains in the region of the end of the glass tubule situated within the glass sleeve.

Abstract: The invention relates to a method and a device for washing textile items to be washed, wherein the items to be washed and a washing liquid are introduced into a washing container. Then the washing container is dually asymmetrically centrifuged. During the dual asymmetrical centrifuging, the washing container is rotated about a first axis of rotation, which extends outside of the washing container, and simultaneously about a second axis of rotation, which extends through the washing container and is at an acute angle to the first axis of rotation. The washing process is thereby intensified and significantly accelerated.

Abstract: Disclosed is a method for carrying out a chemical reaction in a reactor, at least one substance is present in a container that is closed in a gas-tight manner, is introduced into the reactor in said container and is released by breaking open the container. The container is designed such that it breaks open when a specified bursting pressure difference between the internal pressure and external pressure is exceeded. The container is broken open and the substance located in the container is thus released as a result of deliberate application in the reactor of a pressure difference exceeding the bursting pressure difference.

Abstract: Eight containers (1) containing substances (602, 702) are held in holes (71) in a support (70). The eight containers (1) containing different substances or the same substances in different amounts graduated in mole equivalents form a set (69) of containers containing substances, which set can be used for carrying out a chemical reaction.
