Droplet Generation System with Microfluidic Droplet Generator Chips

Droplet generator is the tool for generating micro/sub-micron sized droplets with highly reproducible capacity. PreciGenome Microfluidic Droplet Generation System PG-DG with droplet generator chips can be used for the rapid preparation of water-in-oil or oil-in-water droplets. Compared to conventional methods, it offers the ability to generate droplets with much higher robustness, precision, and repeatability in a cost-effective way. 
The benefits of microfluidic droplet generation can be scaled up to higher throughput. Parallel droplet generators allow high throughput production of monodisperse droplets, fit for applications in the pharmaceuticals, biology, and food industries. With our system, more than 10 million droplets with a diameter of  around 50-120um can be generated using our controller within one hour by using our starter kit. Smaller (< 50um) or larger droplets (>120um) are able to be generated with proper chips and reagents.

Working Principle:​

The system requires two or more unmixable liquid phases, referred to as the dispersed phase, sometimes called the droplet phase, and the continuous phase. The schematic below illustrates the device with junction in focused-flow geometry designed for droplet generation.

Schematic illustration of enlarged junction, controlled break-up droplet at the orifice. The flow through the orifice enables a controlled droplets break-up, which is required for yielding monodisperse micro-emulsions

PreciGenome Microfluidic Droplet Generation System PG-DG with droplet generator chips can be used for the rapid preparation of water-in-oil or oil-in-water droplets. It generates droplets stable, fast and effectively. The droplets are highly uniform in diameter (CV 0.1-5%). The number and diameter of the droplets can be adjusted according to users’ requirements. The size of the generated droplets is mainly controlled by the channels' geometry, the flow rate ratio of two phases, interfacial tension, etc.

Microfluidic Droplet Generator Chips 

PreciGenome offers a variety of droplet generator chips in different materials to meet most of our customers' application requirements.  
Three types of materials, including polymers, glass and silicon, are commonly used to fabricate microfluidic chips. Material of the chip is selected depending on the application requirements, including chip design, types of solvent or reagent used for experiment, needs of the application, budget, and fabrication time,etc. Usually, for research purposes the materials for the chip fabrication generally prioritize performance of the device. For mass production of a products, the factors of production cost, reliability and ease of use are considered first.

In the last decade, the gel particles (hydrogels, microgels, and nanogels) has been an area of interest for many researchers and industries. Because of high throughput, mono-dispersity of particles, and low cost, droplet-based microfluidic systems have been widely used for synthesizing these hydrogel particles.
