Problems solved by technology

However, as shown in Patent Document 2, there are also columns without thread grooves
In addition, if the column sealed by the plug is impacted by dropping or the like, the screw head may be damaged, and only the main body may remain in the column, making it unusable.
In addition, if the column is impacted, the arrangement of the filler inside will be disordered, making it impossible to accurately measure

Embodiment Construction

[0038] The present invention provides a storage container for storing a chromatography column, preferably a column for liquid chromatography such as a column for high performance liquid chromatography (HPLC). The size and shape of the chromatography column housed in the storage container of the present invention are not particularly limited, and in terms of the structure of the container of the present invention described later, as its appearance, it is preferable that the overall length is 20 to 80 mm, and the outer diameter is about 8 to 12 mm. the size of. In addition, the diameter of the liquid passage hole is preferably about 0.1 to 1.5 mm. In addition, if the upper surface and the lower surface of the column are substantially flat, the column can be more stably supported inside the container of the present invention, which is advantageous. The storage container of the present invention can be applied to any type of post having a screw groove on the inner wall of the liq...

Abstract

Provided is a chromatography column contained in a container. The column container is provided with a container body for containing the chromatography column, and a cover engaging the container body. The container body has an internal wall provided with a threaded recess for engagement with the cover. A seal member is provided on each of the internal bottom of the container body and the lower face of the cover. When the cover engages the container body, the cover enters the interior of the container body so as to cause the seal member on the internal bottom of the container body and the lower face of the cover to press the upper and lower faces of the column, whereby the column is fixed within the container body and a fluid passage bore of the column is sealed.

Description

technical field [0001] The present invention relates to a chromatography column housed in a storage container and a storage container for the chromatography column. Background technique [0002] Sample separation and analysis methods represented by chromatography are commonly used in analysis and inspection in the fields of organic chemistry, biochemistry, and medicine. Columns used in chromatography are carefully prepared according to their use and target substances, and careful attention is required for transportation, handling, and storage. [0003] When the column for chromatography is not in use, it is necessary to keep it sealed in order to prevent contamination and drying of the filler inside. When the inner wall of the liquid passage hole of the column has a threaded groove for fluid connection with the analysis device, the column can be sealed by inserting a plug (sealing plug, stopper plug, threaded plug, etc.) into the liquid passage hole.
