Dolomite offers high speed imaging for microfluidics
Dolomite has developed the Meros High Speed Digital Microscope specifically for microfluidic applications. This high resolution imaging system allows users to conveniently monitor high speed microfluidic events, such as droplet formation, using a built-in stage.
The Meros High Speed Digital Microscope features high magnification optics and a zoom lens to ensure that millimetre to micrometre scale features can be visualised clearly, with the added benefit of an extra-long working distance. Coupled with a high speed USB 3.0 camera, this allows clear imaging of moving particles or cells, enabling quantitative analysis of droplet size at low flow rates – typically below 1 kHz – and qualitative evaluation at production speeds of 2-15 kHz or higher, depending on droplet size.
The microscope’s easy-to-use stage is designed to securely hold a wide range of Dolomite and third-party microfluidic devices, including chips, connectors and the µEncapsulator 1 module. An integrated LED coaxial lighting system offers exceptional brightness with very low exposure times, with an optional reversible mirror and diffusor, allowing production of publication-quality images. Illumination from above also leaves the underside of the microfluidic device free for temperature regulation systems, such as the Meros TCU-100 temperature controller. To simplify operation, the entire system is controlled by Dolomite’s intuitive Flow Control Centre software, allowing straightforward live imaging, adjustment and image capture.
