The invention discloses a centrifugal microfluidic emulsification device and a method thereof, wherein the centrifugal microfluidic emulsification device comprises a microfluidic shell, a microfluidic chip built in the inner cavity of the microfluidic shell, and a drive unit. The power device in which the microfluidic chip rotates in the inner cavity of the microfluidic shell, the microfluidic chip is a circular disc body, and an internal phase storage pool is arranged inside, and an internal phase inlet is opened on the upper part of the microfluidic chip And the inner phase inlet is connected with the inner phase storage pool, and a plurality of microchannels are evenly opened between the inner phase storage pool in the microfluidic chip and the outer wall of the microfluidic chip circumference, and the outer side of the microfluidic chip An external phase storage pool and a collection pool for collecting emulsions are arranged between the wall and the inner wall of the microfluidic housing. The microchannels provided on the microfluidic chip are single-layer or multi-layer. One or more microfluidic chips are arranged in the inner cavity. The centrifugal microfluidic emulsification device and method thereof have the advantages of high emulsification efficiency, stable emulsification quality, good emulsification quality, simple equipment structure, low production cost and other advantages that the prior art does not possess.
Description
technical field [0001] The invention relates to the application field of microfluidic technology, in particular to a centrifugal microfluidic emulsification device and a method thereof. Background technique [0002] Emulsification is the effect of one liquid uniformly dispersed in another immiscible liquid with tiny droplets. As the dispersed phase or internal phase (discontinuous phase); the other phase is called the dispersion medium or external phase (continuous phase). Emulsification technology is widely used in various fields of our daily life, such as food, chemical industry, cosmetics, pharmaceuticals and dyes. [0003] The stability of the emulsion has a great relationship with the composition of the emulsion and the size (dispersibility) of the micro-droplets. Since a large number of tiny droplets are produced during the emulsification process, the specific surface area increases greatly, and the emulsification process requires the input of external energy. The m...
