Micronit Microfluidics” four glass microfluidic mixers enable high-quality mixing of micro or nanoliters of fluids, in fractions of seconds. The micromixers extend the Micronit product and technology portfolio with new principles to perform microfluidics experiments. The micromixers are part of the Micronit lab-on-a-chip technology platform. Lab-on-a-chip is the miniaturization of a laboratory to a small chip, enabling fluidic experiments on a microscale. When injecting different fluids into a microchip, the fluids are mixed more by diffusion than by convection. In Micronit’s mixerchips, however, mixing is promoted by the special mixer elements Micronit has integrated into the microchips. Key features of the Micronit micromixers are the very short mixing times — down to milliseconds — and the ideally mixed conditions. The mixers enable fast and effective mixing, even at low pressures. They are based on two mixing principles developed by Micronit and The University of Sheffield: the “Tear-Drop” mixer, for use with low Reynolds number mixing, and the “Swirl” mixer, for use with high Reynolds number mixing. The micromixers are available in four options and can be combined with a lab-on-a-chip kit. This ‘LOAC Micromixer Kit’ enables users to create a complete micromixer setup for immediate start of micromixing experiments.
