    microfluidics valving question

    doh, I also forgot, the other constraint for the single line is there is a single input to the card, and that is pretty much frozen.

    microfluidics valving question

    thanks for the response, my real problem is I have no time to prototype this, but need a well designed text description. I really hate engineering this way but sometimes thats how it goes. I certainly know things never work as well at the bench as on paper. Im getting from your response that...

    microfluidics valving question

    I am trying to spec a project, general theory of operation: have 4 fluids: air(sterile), and 3 aqueous solutions use the air to flush a (semi) ufluidics card between reagents the first two reagents are ~mL washes through the entire card (Q=1200uL/min <or less is ok> ), spec grav~ 1.1 , 0.9 -...
