Problems solved by technology

[0005] In the current liquid droplet mass production device, the on-off of the water-phase flow channel and the oil-phase flow channel is realized by a rotating pull structure or a needle valve structure, but the efficiency of the pull structure is too low and the force is too large. The actual use effect is not ideal

Abstract

The invention discloses a drop product volume production device. The drop product volume production device comprises at least one drop generating unit, the drop generating unit comprises a valve whichis fixedly provided with a plug valve block, the side surface of the plug valve block is provided with a water phase main flow channel and an oil phase main flow channel, which are communicated witheach other and provided with a vertical water phase branch flow channel and a vertical oil phase branch flow channel respectively, and the water phase branch flow channel and the oil phase branch flowchannel penetrate through the plug valve block; the plug valve block is provided with a chip position for placing a micro-fluidic chip; the valve is provided with a chip holder for fixing the micro-fluidic chip and a pressing mechanism for pressing the chip holder; the side of the valve is provided with a pair of valve holes horizontally communicated with the water phase branch flow channel and the oil phase branch flow channel, and a pair of plug valve rods are inserted into the valve holes and provided with through holes; the plug valve rods can rotate to achieve connection and disconnection between the water phase branch flow channel and the oil phase branch flow channel. According to the drop product volume production device, the flow channels can be connected and disconnected simplyby rotating the plug valve rods, so that use convenience can be achieved.

Description

technical field [0001] The invention relates to the technical field of microfluid control, in particular to a droplet mass production device. Background technique [0002] With the development and maturity of droplet control technology, the microfluidic droplet system has become an important platform for chemical and biological research at the microscopic scale, and has been successfully applied to protein crystallization, enzyme analysis, chemical synthesis, single molecule / In the research fields of molecular and cell biology and analytical chemistry such as single cell research, the droplet diameter has a crucial impact on the experimental results in many cases in the above fields. [0003] At present, microfluidic chips have been widely used to generate microdroplets. The researchers used a soft lithography process to fabricate micro-droplet chips with micron scale. First, the researchers used thick photoresist (for example: SU-8 thick resist) and conventional photolit...
