Micropipettor for food detection

Abstract

The invention discloses a micropipettor for food detection. The micropipettor comprises a micropipettor body; the micropipettor body is mainly composed of a pipe barrel, a plunger, a connecting rod and a suction head; the bottom of the pipe barrel is fixedly connected with a connecting pipe; the top of the micropipettor body is provided with the plunger; the connecting rod is arranged in the micropipettor body and fixedly connected with the plunger; the bottom of the connecting rod is fixedly connected with a piston; a spring is arranged in the pipe barrel; the bottom of the micropipettor body is detachably connected with the suction head; the inner top of the suction head is fixedly connected with a separator plate; a plurality of micropores are formed in the separator plate; blocking lamellas are fixedly connected with the inner wall, located above the separator plate, of the suction head, are of semispherical structures and are integrated with the suction head; and a floating ball is arranged between the blocking lamellas and the separator plate. The micropipettor can effectively and accurately extract and transfer a quantified amount of a to-be-determined solution and overcomes the problem of inaccurate detection results due to excess extraction and transfer of the solution; and the micropipettor is accurate in detection results and greatly improves food safety.

Description

technical field [0001] The invention relates to the field of food safety testing, in particular to a micropipette for food testing. Background technique [0002] Food safety is a hot research topic in the world today. Food is the most important thing for the people. Food directly affects people's health and even life. Before food is used, it needs to pass the experimental test of relevant departments to ensure the safety performance of food when eaten. [0003] Food testing has become a hot emerging industry. Food testing mainly detects whether the toxic and harmful substances in food cannot exceed the relevant standards, and minimizes food safety risks. In food testing, the micropipette for food testing is a food testing tool. An essential detection device. [0004] However, due to the lack of industrial mass production of the existing micropipettes, the pipetting accuracy of the pipettes is not accurate enough. In food testing, the sampling volume is not accurate enough, ...
