A container, a nebulizer and a use of an indicator device are described, where the container comprises an indicator device fixedly mounted on the bottom of the container, the container is arranged within the nebulizer and the container can be detached by grabbing the indicator device.

Container, nebulizer and use

A device and a method are proposed for actuating a carpule, in which a piston is displaced in the carpule by means of a ram that is telescopically extensible by rotation, and in this way a liquid medicament formulation is expelled. For carrying out different processes, different operating movements are provided, particularly the operation of an operating element in different directions and/or the operation of different operating elements. This promotes simple, intuitive and safe operation.

Device and method for actuating a carpule

The invention relates to a device and a method for filtering a liquid sample, wherein first capillary-driven filtration occurs and, after initial filling, pressure-operated filtration is performed by applying a vacuum or a positive pressure.

The invention relates to a method for washing at least one cavity () in a microfluidic component, the cavity () containing a first liquid (F) and at least one second liquid (F) being supplied to the cavity () for washing. According to the invention an air bubble (L) is supplied to the cavity () before the washing liquid (F) is introduced. The air bubble (L), which acts as a virtual barrier layer between the first liquid (F) and the washing liquid (F) that follows it enables the washing efficiency to be increased considerably. Overall, this method leads to a saving in washing liquid (F) and washing time. Moreover, a microfluidic component is proposed for carrying out the method.

Method for washing a microfluidic cavity

A microfluidic network having at least one channel which is open on the top side and in which one end of at least one hollow fiber is inserted and a process for making it. For this it is provided that the outside dimensions of the hollow fiber are matched to the inside dimensions of the channel, capillary channels being formed between the hollow fiber and the walls of the channel. The network is covered with a cover film or plate which closes the channel and preferably fixes the hollow fiber temporarily in the channel, and the capillary channels are filled with a fluidically sealing cement. In the area of the inserted end of the hollow fiber, a capillary stop structure is formed so that the cement as it is added it cannot seal the inserted open end of the hollow fiber.

Process and device for coupling hollow fibers to a microfluidic network

A process and a device for determining the viscosity of a fluid are proposed. Very simple and accurate determination is enabled in that the magnetic particles in the fluid are set into vibration by a magnetic field which varies over time. A measurement of the amplitude and/or phase of particle vibration is used to determine the viscosity or an associated quantity, such as the coagulation of blood or the glucose content.

Process and device for determining viscosity

A process and a device for separating and exhausting gas bubbles from a flowing liquid, especially in a microfluidic system, are proposed. Radial deflection of the liquid, a preferably annular deaeration chamber from which gas can escape through gas separation material, and a following discharge filter are characteristic. The discharge filter is made of a hydrophilic material which forms pores or small channels. Optionally, there is an inlet filter of the corresponding material upstream of the deaeration chamber.

An inkjet printhead containing at least one ink channel communicating with a nozzle and defined between two opposed side walls; a membrane interconnecting the side walls; and actuating elements arranged adjacent to the membrane for deflecting the same, wherein the side walls and the membrane are formed by a one-piece member.
