Problems solved by technology

Attachment of the cover to the reaction vessel may lead to interruption of the entire automated method
When removing the attachment of the cover device, this can also lead to a brief lifting of the reaction vessel itself, with the result that the sample liquid may spill out of the recess and thus risk cross-contamination of the sample

Embodiment Construction

[0052] figure 1 The covering device 10 of the first embodiment is shown in a top view in the direction of view on the outer side 12 and in the accompanying sectional views corresponding to the tangents A-A, B-B and in enlarged views I and II. Furthermore, a side elevational view is shown. The cover device 10 is explained simultaneously with reference to different figures, to which no explicit reference is made each time.

[0053] The cover device comprises a main body 14 and an edge section 16 having an upper edge 16a and a lower edge 16b. The two edges 16a and 16b are connected to each other by a protrusion or step 18, wherein the distance from the lower edge 16b to the center 20 of the covering device 10 is greater than the upper edge 16a. In other words, the circumference of the upper edge 16a is smaller than that of the lower edge 16b.

[0054] The covering device 10 comprises a plurality of elastic elements 22 and 24 , wherein the elastic element 22 is arranged along a...

Abstract

The invention relates to a covering device (10), in particular a lid, for covering reaction vessels (50), in particular PCR plates, microtiter plates, and the like, comprising: a substantially flat main body (14) having an inside (34) and an outside (12), at least one planar sealing element (36) arranged on the main body (14) and connected to the main body, wherein the at least one sealing element (36) is arranged on the inside (34) of the main body (14), an edge segment (16), which runs along the periphery of the main body and extends from the outside (12) in the direction of the inside (34) and beyond the inside, and at least one spring element (22, 24) arranged on the main body (14) or on the sealing element (36), which at least one spring element is designed in such a way that the at least one spring element supports the covering device (10) on a surface (54) of a reaction vessel (50) to be covered facing the covering device (10) in the relaxed state of the at least one spring element and that an intermediate space (56) is formed between the sealing element (36) and the surface (54) of the reaction vessel (50).

Description

technical field [0001] The present invention relates to a covering device, in particular a lid, for covering reaction vessels, in particular PCR plates, microwell plates and the like. Background technique [0002] From EP 1 142 795 A2 a covering mat made of elastic material is known, which has a soft base layer arranged together with a support plate for reinforcement. In this case, the support plate is curved in such a way that, under pressure acting on the entire surface of the support plate, it has a curvature-free shape in which the cover mat seals the recess in the reaction vessel in a sealing manner . If the pressure on the support plate is released, it returns to its bent state and is partially lifted from the reaction vessel, so that the support plate can be removed from the reaction vessel with little effort. [0003] Another covering device is known from EP1192995A2, which has a curved support plate and side walls which are hingedly mounted laterally on the suppor...
