mathew "hmm.. Looks like the PCR tubes are close to perfect-- but they're round, which will be troublesome for aligning the laser light path, although we c..." | Read more » over 9 years ago
warren "Huh, interesting! Are they available in materials which don't fluoresce? Do you have a UV laser to test that out with and would you be able to post..." | Read more » over 9 years ago
