Micronit Microfluidics is proud to announce the introduction of a new set of tool kits enabling fast and safe microfluidic experiments. The Microfluidic EOF Kit is a user-friendly set-up for lab-on-a-chip experiments requiring electro-osmotic flow (EOF) in combination with conductivity, electrochemical or fluorescence detection. Two different versions of the kit are available within a few weeks.

The Microfluidic EOF Kit contains two glass microfluidic chips (with or without integrated electrodes), a chip holder enabling electrical connections and high voltage cables. The integrated safety interlock switch ensures that the high voltage sequencer cannot be started without the cover placed on the chip holder. Hence, the Microfluidic EOF kit enables to work safely with high voltage. The bottom of the chip holder is open, making it possible to put it on an inverted microscope for optical inspection or detection.

Both Microfluidic EOF Kits can be used for optical or fluorescence detection. Moreover, the Microfluidic EOF Kit 4515E enables contactless conductivity detection, for instance with on-chip capillary electrophoresis, facilitated by the high voltage electrodes on the microfluidic chips. Capillary electrophoresis is a separation technique that, for instance, has been very successful in the analysis of DNA fragments.

Micronit will show the Microfluidic EOF Kit 4515E during Pittcon 2007, the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. More information can be found on www.micronit.com (go to Products – Microfluidic Tools).
