Reagent prepackaged container capable of centrifugally controlling sequential mixing reaction

Technical Field

The invention relates to a reagent packaging container, in particular to a reagent pre-packaging container capable of centrifugally controlling sequential mixing reaction.

Background

Chemical reagents are relatively standard substances for chemical research and component analysis, are widely used for synthesis, separation, qualitative and quantitative analysis of substances, can be said to be eyes of chemical workers, and can not be separated from the chemical reagents in daily work of factories, schools, laboratories and research institutes, and the chemical reagents are widely applied to various industries of industry, agriculture, medical health, life science, inspection and quarantine, environmental protection, energy development, national defense and military industry, scientific research and national economy.

In-process at chemical reagent's allotment and reaction, all can use mixing arrangement, chemical stirs in mixing arrangement inside, make the chemical intensive mixing reaction in the mixing arrangement, form the required certain chemical raw materials of people, the mixed reaction unit that nevertheless large-scale laboratory was used need mix the reaction to the chemical reagent equivalent of two kinds of differences before mixing, two kinds of chemical reagent that add in the mixed reaction unit are divided the material allotment basically through manual among the prior art, the time overlength of manual branch material allotment, thereby the experimental efficiency has been reduced, also be favorable to realizing the automation that different reagents mix.

Disclosure of Invention

In order to solve the above problems, the present invention provides a reagent prepackaged container for centrifugally controlled sequential mixing reactions that prepackages reagents in the container and controls the sequential mixing of the reagents according to the reaction needs.

In order to achieve the purpose, the reagent prepackaging container capable of centrifugally controlling sequential mixing reaction mainly comprises a reagent container, wherein a reagent chamber higher than the bottom of the reagent container is arranged in 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 arranging the reagent chamber in the reagent container.

In a further aspect, a plurality of reagent chambers having different heights are respectively disposed inside the reagent container. The structure arranges different reagent chambers at different heights so as to respectively distinguish different types of chemical reagents, and when centrifugal driving force is provided for the reagent container through the mixing device, the reaction sequence is controlled according to the sequence of the reagent from the centrifugal rotating shaft to the centrifugal rotating shaft.

According to a further scheme, an L-shaped cavity wall extends from the inner wall of the reagent container, the L-shaped cavity is matched with the inner wall of the reagent container to form a reagent cavity, a semi-closed cavity cover obliquely close to the inner wall of the reagent container extends from the upper portion of the L-shaped cavity wall, and a gap position for flowing out of a reaction reagent during reaction is reserved between the semi-closed cavity cover and the inner wall of the reagent container. According to the structure, the reagent chamber is fixedly arranged on the inner wall of the reagent container, and the semi-closed chamber cover prevents the reagent from flowing out of the reagent chamber before mixing, and meanwhile, the direction of the semi-closed chamber cover can be further optimized for the flowing-out direction of the reagent.

In a further scheme, a sealing cover is arranged at the top of the reagent container, and a dried reagent pad is arranged on the surface facing the inside of the reagent container. The structure prevents the reagent from being thrown out of the container during the mixing reaction through the arrangement of the sealing cover, and the drying reagent is arranged in the sealing cover, so that the effect same as that of a reagent cavity is achieved, and two different chemical reagents are distinguished.

In a further aspect, a reagent is added to the reagent chamber. This kind of structure has reduced the manual time of dividing the material allotment through in the reagent cavity with add reagent to promote experimental efficiency, realized the automation that the reagent mixes.

The reagent prepackaging container capable of centrifugally controlling sequential mixing reaction is designed, a plurality of reagent chambers with different heights are sequentially arranged on the inner wall of a reagent container, reagents are pre-added into the reagent chambers, different chemical reagents are isolated by pre-adding the reagents into the sequentially arranged reagent chambers, and after a proper amount of reagents are added into the reagent containers, a driving force is applied to the reagent containers through a mixing device, the chemical reagents in the reagent chambers and in each reagent container are controlled to be mixed from far to near according to a centrifugal rotating shaft of the mixing device, the reagent prepackaging time in the reagent containers is shortened, so that the experimental efficiency is improved, the sequential mixing of the reagents in the reagent containers is controlled, and the automation of sequential mixing of different reagents is realized.
