Abstract: The present invention relates to a container for storing a reagent, the container comprising: a storage space for reagent (R) comprising a flexible pouch; a passage having a first end (4) that opens onto the outside of the container and a second end that opens into the storage space, the passage being designed to allow a sampling device (20) to access the storage space; a deformable partition (7) that closes off the passage when said partition is not mechanically loaded and which can be loaded by the sampling device to a position in which the passage is open; a seal (6) that is positioned in the passage and comprises an elastically deformable rim (64) defining an orifice (61) that is designed to receive part of the sampling device (20), said rim (64) being designed to establish a seal together with the outer walls of the sampling device when said device is introduced into the passage.

Abstract: The invention relates to a method for imaging a body fluid sample for visual measurements relating to leukocytes, which comprises: —obtaining a measured concentration (WIC) of leukocytes in the sample; —diluting (330) a test solution obtained from the sample, with a dilution ratio (D) determined in accordance with the measured concentration of leukocytes in the sample, so as to obtain an optimum concentration of leukocytes; —rotating (400) the optical chamber containing the test solution by a centrifugation unit, so as to align the leukocytes of the test solution on an optical plane, wherein the optimum concentration of leukocytes for the test solution corresponds to a target surface density of between 20 and 1000 leukocytes per square millimetre on the optical plane; and —imaging (500) the test solution.

Abstract: The invention relates to a transport unit for sample containers which enclose samples to be analysed by an automatic diagnosis unit, the unit comprising: a transportation route (10) of racks (3) of samples, said route (10) extending according to a first direction (A), said route comprising a first end (102) adapted to receive a rack of samples from a first device and comprising a second end (101) adapted to transmit a rack of samples to a second device; a mobile platter (15) comprising a positioning surface extending in a plane; an analysis zone (13) arranged inside the positioning surface, and a waiting zone (12) arranged inside the positioning surface, the analysis zone (13) and the waiting zone (12) being both adapted to receive a rack (3) of samples and being both offset from the transportation route (10); a rack slider (14) configured to move a rack (3) of samples between the transportation route (10) and the waiting zone (12).
