A pack of 3 focused flow (or flow focusing) 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 nozzle sizes of 10 µm, 20 µm, 50 µm or 75 µm.
General
Focused flow droplet generators are widely used in microfluidics to generate highly monodisperse droplets of various sizes. 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
- Three nozzle sizes: 10 µm (9-20 µm droplet range), 20 µm (20-40 µm droplet range), 50 µm (40-90 µm droplet range) or 75 µm (65-140 µm droplet range)*
- Optimized nozzle geometry: etched on both sides (oval shape), 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
*Indicated reference droplet sizes are based on a reference experiment with Silicone oil 5cSt and DI water combined with 2% v/v Tween 20 or Tween 80.
