Dolomite Launches New Droplet Chip

Dolomite, a world leader in microfluidic design and manufacture, has introduced a new range of Small Droplet Chips, glass microfluidic devices which can be used with the Droplet Advanced System to generate highly monodispersed micro-droplets.

Ideal for producing and analysing microemulsions, the innovative Small Droplet Chips are currently the smallest commercial droplet-making chips available, allowing the user to create micro-droplets from 5μm to 30μm in diameter. The devices feature a 14 x 17μm X-junction with hydrophobic and hydrophilic surface properties and benefit from on-chip filters which are provided at chip entry to prevent microchannel blockage.

Microemulsions offer increased stability, a higher interfacial area and the capacity to solubilize both aqueous and oil-soluble compounds. Creating monodispersed microemulsions enables breakthroughs to be made in applications such as food research, materials science and drug delivery, where smaller droplets allow improved control over the targeting and release of active compounds. The near circular microchannel profile at the junction of the Small Droplet Chip is ideal for stable and controllable droplet formation.

Operating over a wide pressure range up to 30bar, the Small Droplet Chips are compatible with Dolomite’s Top Interface 4-way and Linear Connector 4-way, allowing quick and reliable fluidic connection to 1.6mm OD tubing. The Small Droplet Chip is also available in quartz for improved optical transmission.

In addition, Dolomite offers custom solutions for the generation of microemulsions below 3μm in diameter.
