Microfluidic has more than 10 years of experience in making microfluidic droplet generators for all kinds of applications. Droplet generators are excellent tools for generating highly reproducible microsized droplets with much higher precision and repeatability compared to conventional methods.
By tuning the relative viscosities, surface tension, and velocities between the dispersed and the continuous phase droplets of almost any size can be created. Oil-in-water (O/W) droplets can be generated directly using the glass chips. Water-in-oil droplets (W/O) are best formed in hydrophobic channels (coated glass). This to prevent droplets from sticking to the channel walls. Upon request Micronit can coat chips with an hydrophobic anti-stiction coating.
The choice of the correct droplet generator for your application is sometimes not any easy one. There are many variables which can affect the size, frequency and consistency of the droplets produced including:
Microfluidic devices offer a qualitatively superior alternative to conventional macroscale batch processes for the production of highly monodispersed emulsions in a continuous fashion. By means of parallelization, microstructured droplets generators allows high throughput production of monodisperse emulsions for applications in the pharmaceuticals, cosmetics, and food industries.
Micronit offers a range of parallel droplets generators with hydrophilic (native glass) or hydrophobic (coated) channels surfaces for both oil-in-water and water-in-oil systems to satisfy our customer’s needs in their high throughput emulsification applications. Our parallel droplets generators can be designed in a variety of geometries that meet our customer’s requirements. The high accuracy of Micronit’s glass processing technologies combined with a wide range of instruments for high precision surface and size analysis ensures a high quality products with very low intrachannel size and frequency of production variation.
