Embodiment Construction

[0052] figure 1 A sample container in a first embodiment according to the present invention is shown. The sample container 1 includes a housing 2 formed with a mainly cylindrical side surface in a first part (head part 3 ) and in a second part (middle part 4 ). The side surfaces have only a small tapering taper, which is used for easier demoulding of the housing 2 made of plastic after injection molding. The end of the middle part 4 opposite the head 3 adjoins an end 5 in which the housing 2 tapers and is thus tapered in a wider sense. In the end 5 , the housing 2 is formed from an (optical) transparent material, which enables the use of optical measuring elements within the scope of the biotechnological method for which the sample container 1 is used, such as PCR processing.

[0053] On the outside between the head 3 and the middle part 4, the housing 2 forms a shoulder 6 which is used as a bearing surface by which the housing 2 is supported on a sample container support 7 ...

Abstract

The invention relates to a device for closing a sample receptacle with a spherical closure element, said device comprising a storage container for a plurality of spherical closure elements, expelling means for expelling one of the closure elements through an outlet opening of a housing of the device and means for limiting the force exerted by the expelling means on the closure element.

Description

technical field [0001] The invention relates to a device for closing a sample container with a spherical closure element, and also to a system comprising such a device and a corresponding sample container. Background technique [0002] Sample containers are used in particular within the scope of biotechnological methods for processing biological samples or biological material, such as samples containing nucleic acids. These sample containers can eg be used for in vitro replication of nucleic acids within the scope of amplification reactions such as the polymerase chain reaction (PCR). Here, the sample container is used to contain a sample containing nucleic acid. [0003] It is known from the state of the art that within the scope of appropriate biotechnological methods such as PCR, many different sample containers are commonly used as disposable products. Here, the sample container is first filled with sample, then closed in an airtight manner, and finally provided for PC...
