 Small Droplet Chip
Small Droplet Chip,
Small Quartz Droplet Chip
The Small Droplet Chip is a glass microfluidic device designed for generating small droplets in the size range of 5-30μm. The Small Droplet Chip offers a flow focussing junction geometry with 14 x 17μm cross-section at the junction. Applications are found in drug delivery, materials science and food research where smaller droplets allow for the improved control over the targeting and release of active compounds.

Features & Benefits:
Rapid generation of small droplets in the 5-30μm size range
Ideal for producing and analysing micro-emulsions
Near-circular microchannel profile at the junction for stable droplet generation
Hydrophilic coating(Hydrophobic type only)
On-chip filters on inlet channels to prevent blockages
Generates highly monodisperse droplets when used with the Droplet Advanced System
Excellent chemical compatibility
Compatible with Dolomite connectors for quick and reliable fluidic connection
Operating pressure: 30bar
