Problems solved by technology

[0003] During the biological experiment, it is necessary to add different types of reagents or nutrient solutions according to different situations in the process of observing the biological structure and life activity phenomena. Artificially adding nutrient solution during the process will destroy the sterile environment, which may contaminate the cultured microorganisms and cause the experiment to fail. Moreover, when reagents or nutrient solution are added, the reagents or nutrient solution will agglomerate, which is not conducive to the reaction of microorganisms and reduces the Experimental efficiency, and it is impossible to quantitatively add reagents or nutrient solutions according to the situation during the experiment

Embodiment 1

[0048] refer to Figure 1-14 , a liquid adding device based on biological experimental equipment, including a bioreactor 1, a plurality of supports 2 are equidistantly arranged on the top of the bioreactor 1, and the tops of the plurality of supports 2 are fixedly connected with the same placement plate 3, placed A plurality of placement grooves 11 are equidistantly arranged in the plate 3, and reagent bottles 10 are placed in the plurality of placement grooves 11, and one side of the placement plate 3 is provided with a clamping assembly for clamping the reagent bottles 10, and the bioreactor 1 The top of the bioreactor 1 is provided with a connected suction pipe 54, the top of the bioreactor 1 is provided with an extraction assembly for extracting air, the bottom inner wall of the bioreactor 1 is slidingly connected with a bioreactor box 36, and the top of the bioreactor 1 is rotatably connected. There is a stirring rod 41, the outer wall of the stirring rod 41 is provided w...

Embodiment 2

[0062] Embodiment two: if Figure 15 As shown, a liquid adding device based on biological experimental equipment, the difference between this embodiment and Embodiment 1 is that the inner walls on both sides of the bioreactor 1 are rotatably connected with the same plastic wrap tube 50, and one side of the bioreactor 1 The hinge has a door 51, one side of the door 51 is fixedly connected with a sealing layer 52, and one end of the fresh-keeping film tube 50 is laterally attached to one side of the bioreactor 36.

[0063] Working principle: In the first step, pull the first rack 4 outward, and the first tension spring 12 starts to stretch, and the first gear 8 meshes with the first rack 4 and the second rack 7 respectively. The movement of the bar 4 drives the first gear 8 to rotate, and the first gear 8 drives the second rack 7 to move to the right, so that the first splint 5 and the second splint 6 move to both sides, and then the different reagent bottles 10 are respectively...

Abstract

The invention belongs to the technical field of biological experiments, and particularly relates to a liquid adding device based on biological experiment equipment and a use method thereof. According to the scheme, the liquid adding device comprises a bioreactor, a plurality of supports are arranged at the top of the bioreactor at equal intervals, and the tops of the supports are fixedly connected with a same placement plate. The device is simple in structure and convenient to operate, air in the bioreactor can be extracted by pulling a fixed block and a pull rod, low pressure is formed in the bioreactor, a reagent in a reagent bottle is extracted into a metering cylinder, the reagent does not need to be manually added, and microorganisms in the bioreactor are prevented from being infected with external bacteria when the reagent is added; and the amount of the reagent extracted from the metering cylinder can be observed at any time through a transparent glass layer, and in addition, a stirring rod can be driven to rotate to stir a biological reaction box while a rotating shaft is rotated to pour the reagent in the metering cylinder, so that the microorganisms and the reagent are fully mixed, and the reaction speed is increased.

Description

technical field [0001] The invention relates to the technical field of biological experiments, in particular to a liquid adding device based on biological experimental equipment and a method for using the same. Background technique [0002] Biological experiments refer to the process of purposefully observing and studying biological structures and life activity phenomena that are difficult to observe under normal circumstances by using certain instruments, materials and medicines under specific environmental conditions. Biology is a natural science based on experiments. Through biological experiments, not only can help students understand the concepts and laws of biology, and truly learn the basic knowledge of biology, but also help inspire students to think positively, conduct scientific method training, and cultivate students' scientific quality. [0003] During the biological experiment, it is necessary to add different types of reagents or nutrient solutions according t...
