A device and method preparing a sample that may contain a target microorganism, includes: placing the sample in a container including: a device for the capture and/or concentration of a target microorganism or of a protein therefrom, including a capture and/or concentration support; a receptacle including; inlet and fluid guides, a device controlling the sample volume transferred from the fluid guide to the capture and/or concentration device through the inlet orifice, an outlet orifice; the capture/concentration device being attached to a wall of the receptacle; generating a displacement of all or part of the sample to the fluid guide and a defined sample volume from the fluid guide to the capture and/or concentration device, capturing and/or concentrating, on the capture and/or concentration support, the target microorganism or a protein from the microorganism, the volume of sample crossing the capture and/or concentration support then exiting again through the outlet orifice.

Method and device for preparing samples

A microbiological testing device for testing a liquid to be analysed that is liable to contain at least one microorganism, includes a closed inner space, a microbiological filtration member and an inlet port. The device has a nutritive layer in contact with the filtration member, and in that, in a configuration for providing the device an open/close member of the inlet port is in a closed state; the absolute gas pressure inside the closed inner space is strictly less than the standard atmospheric pressure, such that the device is able to create suction through the inlet port during a first opening of the open/close member.

Microbiological testing device, method for provision and use of such a device

A cuvette in which a fluorescent enzymatic reaction can be carried out that is for analyzing a sample includes at least one vertical wall and a bottom. The cuvette is made of a transparent or translucent material and a portion of the cuvette is partially covered on the outside with a sleeve including an inner coating made of retro-reflective material that is in contact with the cuvette.

Analysis cuvette and derivatives with signal amplification

A method for cleaning a test sample well, provided in a diagnostic test card, using a cleaning head having a cleaning tube delivering, at its free end, a cleaning fluid, and a suction tube mounted inside the cleaning tube for aspirating the contaminated cleaning fluid from its free end located in proximity to the free end of the cleaning tube. The method provides for relative displacement between the test card and the cleaning head, so that the test card occupies a cleaning position wherein the cleaning tube delivers, at its free end, the cleaning fluid to the inside of the well to be cleaned and the suction tube aspirates the contaminated cleaning fluid.

Systems for cleaning test sample wells

The invention relates to a device for preparing and/or treating a biological sample including an assembly () of storage chambers () and/or reaction chambers intended for receiving a fluid and means arranged to move an amount of fluid from and/or to at least one of the chambers () of the assembly () of chambers (), the chambers () being separated by walls () so as to form an assembly of adjacent chambers () aligned in a given direction. The means arranged to move an amount of fluid include a needle () connected to a transfer space (), means () arranged to enable the suction of a liquid towards a chamber () from a transfer space () via a needle or delivery from the transfer space () to a chamber (), and driving means () arranged to translate the needle () and the assembly () of chambers relative to one another in the chamber () alignment direction, and in that two adjacent chambers () are separated by a wall including a sealing membrane () or septum capable of being pierced by the needle () and of then recovering the seal thereof once the needle is removed. The invention also relates to a method for manufacturing such a device.
