摘要: Für die Untersuchung von Flüssigkeiten in der Biologie, Biochemie, Chemie, Medizin und Pharmazie werden Verfahren angewendet, die mit erheblichem Aufwand für das Handhaben der Flüssigkeiten und für Hilfsmittel verbunden sind, und die eine Mindestmenge an Flüssigkeit benötigen. Die mikrostrukturierte Plattform enthält Hohlräume und Kapillaren, in denen die Flüssigkeit durch Kapillarkraft transportiert wird.
Plattform zum Handhaben einer benetzenden Flüssigkeit, die auf einem mikrostrukturierten Träger- Hohlräume und ein Kanalsystem zum Transport der Flüssigkeit umfasst, das mit mindestens einem Einlass und mit mindestens einem Auslass versehen ist, und der Querschnitt der Kanäle abschnittsweise in Größe und Form unterschiedlich ist, und - die Kanäle als Kapillaren ausgebildet sind, die in mindestens einer Richtung quer zur Transportrichtung der Flüssigkeit mindestens abschnittsweise eine Abmessung im Millimeterbereich und darunter haben, und - die Wände der Mikrostrukturen zumindest bereichsweise benetzbar sind, - wobei die Plattform folgende weitere mikrostrukturierte Elemente umfasst, die im Transportweg der Flüssigkeit angeordnet sind:. einen fluidischen Schalter mit einem Kapillarstopp am Übergang einer engeren Kapillare in eine erweiterte Kapillare, und mit einer Steuerkapillare, die an den Kapillarstopp angeschlossen ist, und . eine Abtrennvorrichtung für einen Flüssigkeitsteilstrom aus einer Dispersion, wobei diese Abtrennvorrichtung einen Kapillarspalt aufweist, der seitlich an einen Kanal angeschlossen ist.摘要翻译: 平台(1)具有用于运输液体的通道,其中通道的横截面尺寸和形状不同。 通道形成为毛细管(34,42,449)。 在从较窄的毛细管(36,45)到延伸的毛细管(39,48)的过渡处,流体开关设置有毛细管塞(37,46,51)。 控制毛细管(38,47,52)连接到毛细管停止点。 分离装置将部分液体流与分散体分离,并且包括连接到横向通道的毛细管间隙。 分离装置被设计为间隙形导数装置。 毛细管停止点设计为毛细管跳跃的形式。

摘要: The invention relates to a method for measuring the scattered light (L2) of particles (P, PK) in a measuring medium (F), wherein a measuring container (1) is filled with the measuring medium (F) and incident light (L1) is shone through the measuring medium (F) at least in some regions over a certain path length (1) and in a certain direction and the light (L2) scattered from the incident light (L1) is measured within a certain angle range (a). According to the invention, the incident light (L1) is guided parallel to a longitudinal axis (S) of the measuring container (1). By means of said measures, known methods can be improved, and use is possible even for very small measuring volumes of the measuring medium (F) with accompanying small sizes of the measuring container (1).

摘要: A method and a device for the optical examination of a surface region are proposed. Fluorescence measurement is used to determine the amount of a substance bound to the surface region. Light interference is shut out thanks to the surface region being covered with an optically active liquid which filters, reflects, scatters and/or absorbs light with a wavelength at least substantially corresponding to the light radiated in and/or out.

摘要: A device for the intake or manipulation of a fluid, in particular a liquid, and a method for the production of a device of this type is proposed. A flat, not preformed covering film is laminated onto a carrier, wherein a three-dimensionally shaped or convex chamber wall is formed solely by means of the laminating process. Said chamber wall partially forms the boundary of a chamber for the fluid. The device is simple to produce and can be used universally.

摘要: A discharge device and a method for evaporating a liquid to the atmosphere are proposed. The liquid pressurized by gas is supplied to an evaporator (7) via a flow restriction device (5) which restricts the flow rate of the liquid such that continuous release and evaporation surface which is designed preferably by micro structuring such that the surface area is increased and/or the liquid forms an essentially uniform film on the evaporation surface.

摘要: The invention relates to an apparatus for separating blood, more particularly an apparatus (1) for absorbing blood (19) and separating blood components, e.g. blood plasma, as a sample liquid (2). Said apparatus (1) comprises a feeding device (13) for absorbing the blood (2), a device (15) for separating blood components as a sample liquid (2), a duct which preferably absorbs the sample liquid (2) exclusively by means of capillary forces, and a device for filling the duct (3) with sample liquid (2) in an inlet or feeding zone (18) of the duct (3). The separating device (15), in particular a membrane, is curved, especially convexly shaped, and the apex of said curved, especially convex shape projects into the filling device.
