Dolomite Introduces Microfluidic Device for Droplet Generation
Product News Apr 09, 2009
Dolomite has introduced the Mitos Droplet Junction Chip, a glass microfluidic device designed for droplet generation. With two separate droplet junctions, the chip is able to produce a high droplet yield while maintaining consistency in size, the company says.
Compatible with the Mitos Chip Holder H for fast fluidic connection, the droplet junction chip is ideal for monodispersed droplet formation as well as emulsion formation.
Depending on several physical parameters, such as channel size, fluid viscosity and miscibility, total flow rate and flow stability, droplets are typically formed with a diameter between 80 – 120 µm. Furthermore, between 100 – 3,000 droplets can be produced per second in a single channel.
Droplet consistency is easily maintained throughout an application, providing extremely steady and reliable data. With a small size of 22.5 mm x 15 mm x 4 mm (length x width x thickness), the Mitos Droplet Junction Chip provides a straight-through path for droplets, with high visibility. The two junctions within the chip can be used separately or in combination, as suited for various applications.
A range of customized options enable the chip to be tailored to fulfill individual user specifications. As such, it can be provided with a range of geometries, including different channel depths and etchings. As the surface of the channel walls has an effect on the nature of the droplet formation, Dolomite chips are available with hydrophilic, hydrophobic, platinum, or custom coatings.
