Liquid reagent storage box for centrifugal fluid control and micro-fluidic chip structure

Abstract

The invention relates to a liquid reagent storage box and a micro-fluidic chip structure. The storage box comprises a reagent box main body, a reagent box bottom plate and a sealing plug. The reagentbox bottom plate and the reagent box main body are matched with each other and form a storage cavity jointly. The position, away from the rotation center of the storage box, of the storage box is provided with an outlet. The outlet is located in the position, adjacent to the reagent box main body, of the reagent box bottom plate. The storage cavity communicates with the outlet and is used for communicating with the exterior through the outlet. The reagent box bottom plate is further provided with an outflow structure at the outlet. The outflow structure and other structures, adjacent to the outflow structure, of the reagent box bottom plate form a height difference. According to the liquid reagent storage box, on the one hand, through the design of the storage cavity, a liquid reagent needed by centrifugal micro-fluidic control can be stored conveniently effectively; and on the other hand, through the design of the height difference of the outflow structure at the outlet, the completeoutflow of liquid in the centrifugal process can be ensured, reagent waste or shortage is avoided, cost is reduced, and the reaction effect of centrifugal micro-fluidic control is ensured.

Description

technical field [0001] The present application relates to the field of centrifugal fluidics, in particular to liquid reagent storage boxes and microfluidic chip structures for centrifugal fluidics, especially liquid reagent storage boxes and microfluidic chip structures for centrifugal microfluidics. Background technique [0002] Centrifugal fluidics refers to centrifugal liquid flow control, and microfluidics refers to the manipulation of liquids on the submillimeter scale. It integrates the basic operating units involved in the fields of biology and chemistry, and even integrates the functions of the entire laboratory, including sampling, dilution, reaction, separation, detection, etc., on a small chip, so it is also called Lab-on-a-Chip (Lab-on-a-Chip). -a-Chip). This kind of chip is generally composed of various liquid storage pools and interconnected microchannel networks, which can greatly shorten the sample processing time, and realize the maximum utilization efficie...
