[DIYbio] Re: Cheap capillary electrophoresis


 
I can't see from the video the other end of the tube and if that is in liquid. Anyway I did use similar thing (it's somewhere on this board). It turned out that optical detection is hard (material issues with UV, lamps are expensive, power is demanding...) so I found out most people work with dielectric detection. There are number of papers for portable, cheap electrophoresis based on this (if you need them I can dig them out).  For DNA you do need gel-like sieving medium like some big polymer along with the buffer again there are papers for this.
