Pre-packaged reagent containers for centrifugally controlled sequential mixing reactions

Abstract

The invention relates to a reagent pre-packaged container capable of centrifugally controlling sequential mixing reactions. A plurality of reagent chambers with different heights are sequentially arranged on the inner wall of the reagent container, and reagents are pre-added in the reagent chambers. Different chemical reagents are isolated by pre-adding reagents in the sequentially arranged reagent chambers. After adding a proper amount of reagents in the reagent container, a driving force is applied to the reagent container through a mixing device to control the mixing of chemical reagents in the reagent chamber and chemical reagents in the reagent container in a sequence from far to near from a rotating axis. Pre-packaged reagents in the reagent container reduce the time for manual material distribution and mixing, and control the sequential mixing of reagents in the reagent container, thereby improving the experimental efficiency and realizing the automation of sequential mixing and reaction of different reagents.

Description

Technical Field

[0001] The invention relates to a reagent packaging container, in particular to a reagent pre-packaging container capable of centrifugally controlling sequential mixing reactions. Background Art

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. They can be said to be the eyes of chemists. In the daily work of factories, schools, laboratories and research institutes, chemical reagents are indispensable. Chemical reagents have been widely used in industry, agriculture, medical care, life sciences, inspection and quarantine, environmental protection, energy development, national defense and military industry, scientific research and all walks of life in the national economy.

[0003] In the process of preparing and reacting chemical reagents, a mixing device is used. Chemicals are stirred inside the mixing device so that the chemicals in the mixing device are fully mixed and reacted to form a certain chemical raw material required by people. However, the mixing reaction device used in large laboratories requires equal mixing of two different chemical reagents before mixing. In the prior art, the two chemical reagents added to the mixing reaction device are basically manually divided and prepared. The time for manual division and preparation is too long, which reduces the experimental efficiency and is not conducive to the automation of mixing different reagents. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a reagent pre-packaged container in which reagents are pre-packaged and the reagents can be mixed sequentially according to reaction requirements and can be centrifugally controlled to perform sequential mixing reactions.

[0005] In order to achieve the above-mentioned purpose, the reagent pre-packaged container designed by the present invention can be centrifugally controlled to sequentially mix and react, mainly comprising a reagent container, wherein the reagent container is provided with a reagent chamber higher than the bottom of the reagent container. This structure controls the reaction sequence of the chemical reagent in the reagent chamber and the chemical reagent at the bottom of the reagent container by providing the reagent chamber in the reagent container.

[0006] A further solution is that a plurality of reagent chambers of different heights are arranged inside the reagent container. This structure arranges different reagent chambers at different heights, thereby distinguishing different types of chemical reagents. When the mixing device provides centrifugal driving force to the reagent container, the order of the reactions is controlled according to the order of the reagents from far to near the centrifugal rotating axis.

[0007] A further solution is that an L-shaped cavity wall extends from the inner wall of the reagent container, and the L-shaped cavity wall and the inner wall of the reagent container cooperate to form a reagent chamber, and a semi-closed cavity cover extends from the upper part of the L-shaped cavity wall and is close to the inner wall of the reagent container obliquely, and there is a gap between the semi-closed cavity cover and the inner wall of the reagent container for the reaction reagent to flow out when the reaction occurs. This structure fixes the reagent chamber on the inner wall of the reagent container, and prevents the reagent from flowing out of the reagent chamber before mixing through the semi-closed cavity cover, and the direction of the semi-closed cavity cover can also further optimize the direction of the reagent outflow.

[0008] A further solution is that a sealing cover is provided on the top of the reagent container, and a drying reagent pad is provided on the surface facing the inside of the reagent container. This structure prevents the reagents from being thrown out of the container during the mixing reaction by providing the sealing cover, and the drying reagent is provided in the sealing cover, achieving the same effect as the reagent chamber, and distinguishing two different chemical reagents.

[0009] A further solution is that reagents are added into the reagent chamber. This structure reduces the time of manual material distribution and mixing by adding reagents into the reagent chamber, thereby improving the experimental efficiency and realizing the automation of reagent mixing.

[0010] The reagent pre-packaged container capable of centrifugally controlling sequential mixing reactions designed by the present invention has a plurality of reagent chambers of different heights arranged in sequence on the inner wall of the reagent container, and reagents are pre-added in the reagent chambers. Different chemical reagents are isolated by pre-adding reagents in the reagent chambers arranged in sequence, and after adding a proper amount of reagents in the reagent container, a driving force is applied to the reagent container through a mixing device to control the mixing of the chemical reagents in the reagent chambers and in each reagent container in a sequence from far to near from the centrifugal rotating axis of the mixing device. Pre-packaged reagents in the reagent container reduce the time for manual material distribution and preparation, thereby improving the experimental efficiency, and the reagents in the reagent container are controlled to be mixed sequentially, thereby realizing the automation of the sequential mixing of different reagents.
