Quantitative dropping device for molecular detection reagent

Abstract

The utility model relates to molecular detection reagent technical field, and disclose a kind of quantitative dropping device of molecular detection reagent, including container, the container outside is provided with control assembly, the control assembly includes the first connecting pipe of fixed connection in container bottom, the first connecting pipe is communicated with container interior, the first connecting pipe bottom is fixedly connected with the temporary storage pipe.The utility model when filling liquid to container interior, the air in container interior can enter the inside of temporary storage pipe, and drive liquid to enter the inside of temporary storage pipe, to store part liquid and air by temporary storage pipe, and the existence of temporary storage pipe makes liquid to enter the inside of temporary storage pipe, need to first expel the air in the inside of temporary storage pipe, to reduce the flow rate of liquid, and when the weight of liquid is insufficient, liquid cannot expel the air in the inside of second connecting pipe, to make liquid not directly along second connecting pipe to outside, to reduce the possibility of liquid waste.
