A device for implementing a test card inside which sequential reactions and fluid transfer operations are performed under the effect of a control integrated into the card; the card includes at least two sequential reaction systems arranged in parallel, each reaction system having at least two fluid transfer systems arranged in series. A test card and the method for implementing the device and the card are also disclosed. The device contains at least one actuator per reaction line, and all the actuators are at a regular distance from one another, with the actuators preferably being equidistant. The invention is particularly applicable for the micromanipulation of fluids in biological applications.

Device for implementing an analysis pack, analysis pack and method using same

An apparatus () which includes at least one planar surface () having compartments () which are defined by a partition (), the compartments creating a space which makes it possible to displace at least one liquid sample (and/or) and, when there are at least two liquid samples (and), makes it possible to displace them both in an independent way and bring them together so that they can react with one another. The compartments () include at least two different types of groove: a deep groove (), capable of partitioning the sample(s) (and/or), and a shallow groove capable of receiving the sample (s) (and/or), the two types of groove (and) making it possible to direct sample movements (and/or) by altering the orientation of the apparatus (). The invention is particularly applicable for the micromanipulation of fluids in biological applications.

Apparatus enabling liquid transfer by capillary action therein

A method for drawing a biological sample using a suction-discharge device, such as a manual or automatic pipette, built into an automated device or not. A method for detecting the free surface of a biological sample and/or solid, a sample drawing device such as a pipette and a device for detecting the free surface of a biological sample or a solid are also disclosed. This method includes actuating a means causing a pressure variation or an air flow within the suction-discharge device, positioning the lower free end of the device in such a way so that it becomes flush with a free surface of the biological sample, measuring an overpressure within the suction-discharge device, and sampling a quantity of the sample by suction using the device. The invention finds a preferable application in the field of automatic analyzers.

Biological sampling method

The invention provides a method and device for decontaminating a contaminated hollow metal needle having electrical wires attached to the needle which heat cleaning fluid dispensed into the needle.
