Description

Technical Field

[0001] The invention relates to the field of chemical experimental equipment, in particular to a device for controlling the sequential mixing reaction of reagents through centrifugal force. Background Art

[0002] Reagents, also known as biochemical reagents or test drugs, are mainly pure chemicals used to achieve chemical reactions, analytical tests, research experiments, teaching experiments, and chemical formulas. They are generally divided into general reagents, high-purity reagents, analytical reagents, instrumental analytical reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion colorimetric reagents, etc.

[0003] In the prior art, the preparation and reaction process of chemical reagents requires that the chemicals in the reaction tube be shaken to allow different chemicals to be fully mixed and reacted. However, manual shaking takes a long time and is prone to splashing of reaction reagents during the shaking process. Manual shaking can only shake one container at a time. Manual shaking will cause problems such as insufficient and low efficiency of shaking, and is not conducive to realizing the automation of solution mixing reactions. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a device that drives the rotation of a reaction tube through a centrifugal device, thereby shaking the chemical reagents in the reaction tube, making the chemical reagents in the reaction tube fully integrated, and ensuring that the reagents in the reaction tube are mixed and reacted in sequence, and controlling the sequential mixing reaction of the reagents through centrifugal force.

[0005] In order to achieve the above-mentioned purpose, the device designed by the present invention controls the sequential mixing reaction of reagents by centrifugal force, mainly comprising a centrifugal support, a centrifugal shaft is fixedly arranged in the middle of the centrifugal support, and a plurality of reaction tube placement grooves arranged obliquely are opened on the inner side of the centrifugal support, and the plurality of reaction tube placement grooves are uniformly distributed around the centrifugal shaft, and the distance from the notch of the reaction tube placement groove to the centrifugal shaft is greater than the distance from the bottom of the reaction tube placement groove to the centrifugal shaft. The setting of this structure controls the flow direction of the reagents in the reaction tube during the reaction process through the oblique reaction tube placement grooves, thereby ensuring that the reagents in the reaction tube are mixed and reacted in sequence.

[0006] A further solution is that the centrifugal support is provided with a reaction tube fixing buckle for preventing the reaction tube in the reaction tube placement slot from being thrown out due to centrifugal force. This structure is arranged to fix the reaction tube in the reaction tube placement slot by the arrangement of the reaction tube fixing buckle.

[0007] A further solution is that an L-shaped connecting arm is provided at one end of the reaction tube fixing buckle, the L-shaped connecting arm cooperates and fixes with the reaction tube placed in the reaction tube placement groove, and a J-shaped undercut is provided at the other end of the reaction tube fixing buckle to cooperate and fasten with the centrifugal support. This structure is set up to seal the tube opening of the reaction tube through the L-shaped connecting arm in the reaction tube fixing buckle, and further fix the reaction tube in the reaction tube placement groove through the J-shaped undercut, thereby preventing the reaction tube from flying out of the reaction tube placement groove during the reagent reaction process.

[0008] A further solution is that the centrifugal support is connected to the L-shaped connecting arm via a hinge. The arrangement of this structure controls the switch of the reaction tube fixing buckle through the arrangement of the hinge.

[0009] The device designed by the present invention controls the sequential mixing reaction of reagents by centrifugal force, fixes the reaction tube in the reaction tube placement groove by a reaction tube fixing buckle, and drives the reaction tube to perform circular motion by a centrifugal rotating shaft, so that the chemical reagents in the reaction tube are fully integrated, ensuring that the chemical reagent mixing reaction is fully carried out, and at the same time, the reaction tube placement groove arranged obliquely can adjust the flow direction of the reagents in the reaction tube, thereby ensuring that the reagents in the reaction tube are mixed and reacted in sequence; and multiple reaction tube placement grooves are simultaneously arranged in the centrifugal support, so that the device can perform comparative tests on the chemical reagents in multiple reaction tubes at the same time.
