Microfluidic device with microvalves [Folch lab]

[folchlab]

this paper was published in:

Cooksey, G.A., Sip, C.G., and Folch, A., "A multi-purpose microfluidic perfusion system with combinatorial choice of inputs, mixtures, gradient patterns, and flow rates", Lab on a Chip 9, 417 (2009).

The channels are about 100 micron wide each. The paper on pumps was just accepted in Lab on a Chip too, so it will be in press in a month or so.

@folchlab: Awesome! How did you analyze the fluid flow? Using Matlab or any other kind of softwares? Did you do any sort of simulation of the design before making it? Thanks!

what scale are we looking at? and the valves?

[folchlab]

yes, we also use elastomeric peristaltic pumps. More on that soon! (we are about to publish a paper)

@folchlab

From what journal will this paper be publish in? I cant wait to read about it!

Hi..i'm a mechanical engineer too, and it's totally awesome what you do. Can I ask you if you use elastomeric peristaltic pumps?have you videos of them?

As a mechanical engineer, I find your videos and work really interesting! You have an innovative approach to research and the publication of your results (ie. equaliser microreactor!).

How many elastomeric valves are you using in this setup? Is the working fluid just food dye and water? I'd find it very strange if you were able to achieve sublaminar flow with the latter!!!

thanks for your interest! there are 8 microvalves that control 16 inlet in a multiplexer, plus a few more microvalves to control other functions. you can read how this device works in detail in the following publication: Cooksey, G.A., Sip, C.G., and Folch, A.
