Easy, Quick Method for Making a Microfluidic Device

- Using simple tools and a membrane cutter, we build a Y-shaped microfluidic device. The assembly takes about 10 minutes plus the drying time for epoxy glue. The channel volume in this example is about 22 uL. The device layout can be readily changed to fit your project.

I tried it. It worked well. Thanks!
Very Nice!
In the published paper it looks like the setup includes 4 screws on the corners to seal the device. Are those necessary?
Great !
where did you purchase the barb fittings?
by now we are using cut pipette tips which work as well and are cheaper (the original supplier of the barb fittings was Cole-Parmer)
Thank you for sharing this. At the end of the video I can't understand why the flow in the channel is like a very thin line?!
Two solutions are co-flowing along the channel. Along their interface a thin precipitate membrane grows.

Thanks a lot. Could I ask other questions:
At the outlet how do you separate precipitation from unreacted precursor solutions?
And a micromixer is different from a microfluidic device?
Hello! Thank you for sharing this. What's the name of the paper/adhesive used?
Hi Maria, here is a list of supplies that we use (hope this helps ... and ... we don't get money for the links):
(1) Two barb fittings ( or cut-off pipet tips)
We purchased FITM331 from this website: www.nresearch.com/products/fittings/barb-zerodead.html.
(2) Epoxy glue: Gorilla 2 Part Epoxy, 5 Minute Set, .85 ounce Syringe, Clear.

(3) Parafilm All Purpose Laboratory Film

(4) VWR plain micro slide: VWR 48300-026

(5) Tygon tubing E3603 1/16" ID x 1/8" OD x 1/32" Wall

@@SteinbockGroup Thank you so much!!!, greetings from Peru.
Hello, which machine did you used for cutting the parafilm?
Hi Material 1527, the link is at the bottom of the video description.
Can a similar setup be used in reverse? For splitting/separating?
You can separate by size but separating a precipitated molecule into its previous components is not possible unless you do it chemically
Hi, I really liked you video.
I am working on microfluidic channel, and I would like to ask you about the slides you used and the machine from which you cut the parafilm.
Can you please provide more details of the cutter, how thin can it cut?
Cab u give a detailed written procedure with exact amount
Look at the DOI link in the description, it's free access
