Description
Background technique
Microfluidic chip technology is preparation, reaction, detection, separation of sample in fields such as biology, chemistry, medical treatment etc. one
For sequence of maneuvers set into one piece of micro-fluidic chip, currently marketed micro-fluidic chip passes through capillary, siphon and centrifugal principle
Make sample and the reagent flow combinations in micro-fluidic chip, either capillary, siphon or centrifugal principle requires certain behaviour
The combination of sample and reagent can just be made by making the waiting with a period of time.
Liquid-transfering gun is one kind of pipettor, is usually used in that laboratory is a small amount of or micro liquid pipettes, specification is different, difference rule
The liquid-transfering gun of lattice matches different size of pipette tips, and the shape of different manufacturer's productions is also slightly different, currently on the market
Liquid-transfering gun be all by aerodynamics, pass through atmospheric pressure extract or release liquid.Liquid-transfering gun currently on the market is inhaled
It takes or the liquid that discharges is deposited in the containers such as reagent bottle, sample cup, centrifuge tube, test tube mostly, and its major function
It is provided to liquid relief, is directly used on the liquid-transfering gun and suction nozzle Vehicles Collected from Market of micro-fluidic chip not yet.
Utility model content
To solve the above-mentioned problems, the utility model discloses a kind of liquid-transfering gun power and driving miniflow plate.
The technical solution of the utility model are as follows: a kind of liquid-transfering gun power and driving miniflow plate, including miniflow plate entrance, miniflow
Plate entrance opening circulates with miniflow plate surface straight up, and miniflow plate entrance includes miniflow plate entrance I and miniflow plate entrance II, micro-
Flowing plate entrance I is connected with miniflow plate entrance II by fluid channel I, and the middle position of fluid channel I is communicated with fluid channel II vertically,
Fluid channel II is located at the lower section of fluid channel I in perpendicular, and fluid channel II is in serpentine, and serpentine turning is rectangular, miniflow
The distance of lower a distance miniflow plate surface of road II is greater than the distance of the preceding paragraph, and shape is in rank to fluid channel II in perpendicular
The end of scalariform, fluid channel II is exported equipped with miniflow plate, and miniflow plate is exported with miniflow plate entrance in the same horizontal line, miniflow plate
Exit is equipped with liquid-transfering gun, and liquid-transfering gun lower end is equipped with suction nozzle, and suction nozzle is located in the outlet of miniflow plate.
Further, the position of the middle position fluid channel II, i.e. miniflow plate entrance and miniflow plate outlet same horizontal line is set
Reagent point is set, reagent point is in perpendicular perpendicular to miniflow plate surface.
The usefulness of the utility model: the application can fast implement reagent and sample in micro-fluidic chip and quickly combine
And separation, than traditional centrifugal process, capillary method is more rapidly and efficiently, easy to use.
