摘要:
The invention relates to a metal spray can, which is ergonomically designed, in order to ensure a safe holding of the can when spraying the contents. This spray can comprises a lower (11) and upper can section (12), whereby the lower can section (11) contains a bottom and is nearly cylindrical so that a cross-section of the spray can is circular in this section. The upper can section contains a shoulder area (14) and a can opening (15) with a collar (16) for an insertable spraying system out of which the contents of the can are discharged. In order to obtain an easy-to-handle spray can, which is ergonomically shaped and thus has no drawbacks with regard to safety, the invention provides that the upper can section additionally contains a shaping area (17) that can also extend over the shoulder area. A cross-section in the shaping area of the spray can is designed differently to the nearly cylindrical cross-section of the lower can section. The invention also relates to a device (20) that serves to produce said spray can. The invention additionally relates to a method for producing the inventive spray can involving the use of the corresponding device.
摘要:
Discharge device for dispensing fragrance or the like comprising capillary tube for supplying liquid from reservoir to an evaporator's surface. The capillary has specific geometric properties concerning hydraulic diameter and length. In the capillary's flow channel a valve, filter or constriction may be integrated. Further, an evaporator is disclosed comprising a capillary for supplying the evaporation surface with liquid. The surface comprises micro-channels for uniform fluid film formation.

A membrane structure for gas separation, a degassing device having such a membrane structure, and also method for production of the same are proposed. A porous carrier layer is joined flat to a thin polymer membrane, in particular made of amorphous PTFE. In particular, the polymer membrane is produced on or from the carrier layer. This makes possible a simple and inexpensive structure and also an effective gas separation. Particularly preferably, the polymer membrane is formed by applying a polymer solution in the liquid state to the carrier layer and drying it.

A discharge device with a metered dose valve is proposed. The metered dose valve comprises an inlet valve, a metering chamber and an outlet valve. In order to allow discharge of fluid from the metering chamber in multiple steps, a user can depress and release an actuation member multiple times in a selected discharge state wherein refill of the metering chamber with new liquid is prevented.

Disclosed are a device and a method for analyzing a sample liquid, particularly the ELISA method being very easy, fast, and highly accurate to carry out. According to the invention, a sample liquid and a diluting liquid are fed to several dosing chambers having different volumes such that the sample liquid can be diluted into associated reaction chambers at different dilution ratios in a dilution step. Different liquids can be delivered successively to the reaction chambers by means of a common receiving chamber. The liquids are transferred from the reaction chambers into associated test chambers in order to stop the detection reaction.

摘要:
This invention relates to a process for producing a multiplicity of micro fluidic arrangements (1) from a plate-shaped composite structure, wherein each arrangement comprises a groove structure (4) which forms flow channels and the dimensions of which are in the micrometre range. The lines (6) for the optional subsequent mechanical separation of bridging groove structures (4) are joined to each other and are partly or completely filled with a filling medium (7) before mechanical machining. The medium (7) is selected so that it is not removed from the groove structures (1) either by the mechanical machining or by aids used during mechanical machining. Afterwards, however, the filling medium (7) is removed from the groove structures (6) by suitable measures. The groove structures (4) are thereby prevented from becoming blocked due to mechanical contaminants. An atomiser which is provided with the nozzle arrangement is also proposed.
摘要:
Es werden ein Verfahren und eine Vorrichtung zur Bestimmung der Viskosität eines Fluids vorgeschlagen. Eine sehr einfache und genaue Bestimmung wird dadurch ermöglicht, daß magnetische Partikel (3) im Fluid (2) durch ein zeitlich variierendes Magnetfeld (6) in Schwingung versetzt werden. Eine Messung der Amplitude und/oder Phase der Partikelschwingung wird zur Bestimmung der Viskosität oder einer damit zusammenhängenden Größe, wie die Gerinnung von Blut oder ein Glucosegehalt, verwendet.
