Embodiment Construction

[0043] As shown more particularly in the figures, the object of the invention relates to a closure element 1 intended for use with a container 2 receiving a chemical or biological solution to be analyzed. according to Figure 8 A preferred application is shown, the container 2 is in the form of a microwell plate with a series of wells 3 each intended to receive a chemical or biological solution to be analyzed. The closure element 1 comprises for each hole 3 a plug 4 according to the invention, which plug is in the Figure 1 to Figure 4 is shown in more detail.

[0044] Each plug 4 comprises an insert sleeve 5 intended to be engaged in the hole 3 by elastic deformation. This insert sleeve 5 is tubular or cylindrical with a circular cross-section, the diameter of which is adapted to the diameter of the hole 3 in order to ensure a tight fit by means of the elastic deformation of the plug in the hole. Accordingly, the sleeve 5 has an outer surface 5e and an inner surface 5i.

Abstract

The invention relates to a closure element (1) for a well for receiving a chemical or biological solution to be analysed, comprising, for each well, a plug (4) comprising an insertion skirt (5) taking the form of a cylinder provided with two truncated regions (15) formed in a symmetrically opposite manner on the outside of the skirt to form vents, this insertion skirt (5) being provided with an end wall (9) in which there is formed a through-cutout (18) oriented radially in the direction of the two truncated regions (15).

Description

technical field [0001] The object of the invention relates to the technical field of handling fluid samples in chemical or biological processes in general, and more specifically to the field of diagnostic kits for chemical or biological solutions to be analyzed. Background technique [0002] Patent US6500390 relates to the technical field of microwell plates intended to receive and prevent loss of fluid samples during the different processing steps. Such a microplate comprises containers, each provided with a plug adapted to contain a fluid sample inside the container, regardless of the position of the microplate. Each plug is also provided with a central opening constituting a vent to allow the container to communicate with the outside. Due to the presence of vents, such microplates cannot guarantee a complete seal, which poses a risk of contamination of fluid samples. [0003] Patent application WO2015 / 059254 describes a lysis kit (lysis kit) and for preparing a sample, ...
