A pack of 3 classic focused flow (or flow focusing) single-etched droplet generators in glass with topconnect interface to be used with the Micronit Fluidic Connect Pro chip holder.
Available uncoated (hydrophilic) for oil-in-water or with a hydrophobic coating for water-in-oil, and with different channel sizes.

Focused flow droplet generators are widely used in microfluidics to generate highly monodisperse droplets of various sizes. This classic droplet generator is single-etched, creating a semi-oval channel shape. A new droplet generator, with a nozzle etched on both sides, is available for better performance.

Droplet Generator - nozzle design

Nozzle design of the Classic Droplet Generator

Two channels sizes are available:

  • Small (droplet range 10-60 µm): nozzle height: 10 µm, channel width: 100 µm, channel height: 20 µm
  • Large (droplet range >50 µm): nozzle height: 50 µm, channel width: 500 µm, channel height: 100 µm

This Micronit chip offers the following features:

  • Manufactured from high-quality borosilicate glass, inert to most chemicals and biocompatible
  • Precision-etched microfluidic channels for reproducible results
  • Single-etched nozzle, stable and highly monodisperse droplet generation
  • Uncoated (hydrophilic) for oil-in-water (O/W) droplet generation, or coated (hydrophobic) for water-in-oil (W/O) droplet generation

Easily change the droplet size and frequency by tuning the flow rates of the dispersed and continuous phases. These chips are suitable for foam, digital PCR, single-cell analysis, encapsulation, particle and nanoparticle production, etc.

For optimal performance, the droplet generator should be used as follows:
