Abstract

The invention relates to a multi-module emulsion droplet generation control device. The device comprises: a replaceable pressure generation module comprising a positive pressure generation module, a negative pressure generation module and a positive and negative mixed pressure generation module which are independently arranged; a proportional valve detachably connected with the replaceable pressure generation module; and a fixed plate fixedly provided with a plurality of gas channels, wherein one end of each channel is communicated with the proportional valve, the other end of each channel isprovided with an electromagnetic valve, and all the electromagnetic valves form an electromagnetic valve array. The device is characterized in that multi-module, multi-channel or single-channel independent generation is realized, emulsion droplets are generated without polluting a compression pump or a vacuum pump, droplet sizes are uniform and controllable, and a generation rate is stable; and the device can realize generation of single-channel droplets and continuous generation of multi-channel droplets, and is convenient and flexible to use and capable of controlling the sizes of droplets.

Description

technical field [0001] The application relates to a multi-module emulsion droplet generation control device, which is used for controlling the emulsion droplet generation of a microfluidic chip, and belongs to the technical field of biological detection. Background technique [0002] Emulsion droplet technology is a micro-nano technology that uses the interaction between flow shear force and surface tension to divide continuous fluid into discrete emulsion droplets of nanoscale and below in microscale channels. It is a new technique for manipulating the volume of emulsion droplets developed in recent years. [0003] The basic process of emulsion droplet formation is: two immiscible liquids, one of which is used as the continuous phase and the other as the dispersed phase, and the dispersed phase is formed in a tiny volume (10 -15 -10 -9 L) The form of the unit is dispersed in the continuous phase, forming droplets that move within the channel. [0004] Most of the existin...
