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 supplied 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 (α).It is provided according to the invention that the incident light (L1) is guided parallel to a longitudinal axis (S) of the measuring container (1).By these measures, known methods can be improved and it is readily possible to use the invention even for very small measuring volumes of the measuring medium (F) with the associated small dimensions of the measuring container (1).

摘要： The invention relates to a container (1) for a fluid for metering a reagent into a microfluidic system. The container comprises a chamber (4) and a first film (3) which seals off the chamber (4) so that the fluid is encapsulated in the chamber. Advantageously, the first film (3) is an aluminum sealing film. A second film (7) is sealingly arranged on the first film, for example by adhesive bonding of the film layers. The films differ in their tear strength such that when pressure is applied simultaneously to both films the first film tears while the second film deforms elastically and/or plastically. By tearing the first film a connection is produced between the container chamber and an inlet channel so that a fluid contained in the chamber flows into the microfluidic system.

摘要： The invention relates to joining plastic components into a microfluidic cartridge (20). The invention in particular relates to cartridges (20) for diagnostic analysis devices. The cartridge (20) comprises a fluidically conductive floor element (11), a cover (2), and a film (3) disposed between the elements (1, 2). The cover (2) or the floor element (1) and the film (3) comprise a filling opening (5) for filling microfluidic channels (4) in one of the elements having sample fluid. Pins (6) formed integrally with one of the board-shaped elements (1, 2) engage in corresponding holes (7) in the film (3) and the associated element (1, 2) for each.By means of deforming a pin (6), a friction fit is produced between a deformed pin and the wall of a hole, and a head (9) contacting the associated substrate in a form-fitting manner is formed. For the joining process, a press tool (12) is placed on a head end (9) of a pin (6) at a predetermined pressure P, and heat transfer into the pin (6) takes place during a weld time tS. The pin material is brought to above the glass transition temperature and/or the melting point, and a friction fit between the pin (6) and the wall of the hole (7) is formed by flowing the pin material in the hole (7).

摘要： A microfluidic device and a method of producing it are proposed, in which a film covers a chamber in a carrier. The film is locally re-tightened in the region of the chamber after the film has been secured to the carrier. In this way it is possible to prevent undesirable bulging of the film into the chamber.

摘要： The invention relates to a device for sample separation, particularly for blood separation, in which the sample liquid is introduced into a feed device. The sample flows vertically through a separating device such as a filter or a membrane, so that sample particles are retained and separated off.The sample liquid thus separated, particularly blood plasma, is received by an inlet chamber underneath the separating device and conveyed by means of a channel in the lateral direction out of the inlet chamber.Particularly advantageously, the channel extends into the inlet chamber, the channel being formed by a recess in the base of the inlet chamber.

摘要： The invention relates to a microfluidic structure (1), comprising at least one cavity (10) having at least one inlet opening (11) and at least one outlet opening (12), wherein the cavity (10) can be filled with a liquid or a liquid can flow through the cavity and at least one element (13) is provided inside the cavity (10), which element stops the flow of the liquid at least temporarily and/or diverts the flow of the liquid at least in some regions within the cavity (10).According to the invention, the at least one element (13) is formed by a recess (13) introduced into a wall of the cavity (10), which recess (13) has at least one first region (14) at which the liquid stops at least temporarily and/or is diverted at least in some regions and at least one second region (15) at which the liquid preferably flows into the recess (13).Such a microfluidic structure makes it possible to fill the cavity (10) without air inclusions. Thereby, the useful volume of the cavity (10) is not limited, and the production costs of a microfluidic component (2) having such a microfluidic structure (1) can be kept low.
