Micro-pipette tip for forming micro-droplets
A micro-droplet-emulsifier to generate a micro-droplet-emulsion for application on digital polymerase chain reaction is provided. This device includes a micropipette to hold a dispersed-phase-liquid; a droplet generator that attaches to the micro-pipette and has a plurality of substantially flat micro-channels. The dispersed-phase-liquid is forced through the micro-channels to form micro-droplet-emulsion of dispersed-liquid-phase in the continuous-liquid-phase inside the chamber. The size of the micro-droplets is controlled by the shape and the aspect ratio of the micro-channels, the depth of the micro-channels and the material of the micro-droplet-generator-head that dictates the contact angle of the droplet on the micro-channels.
