Glass is a fine material. You know how incandescent lamp bulbs are made in various controlled shapes...so,
is there a source of glass vials 6-8mm diameter that could be capped with plastic snap on lids?

Hmmm.... yes, here are 200/$36, or about 0.22 USD each:
http://www.sigmaaldrich.com/catalog/product/aldrich/z291994?lang=en&region=US 8 × 40mm, 1mL vol. Constructed of clear
borosilicate glass. Vials come with LDPE snap-plug caps.

These would be good to design a system around. I'd prefer a little shorter than 4cm though.

Here are shorter ones. http://www.biotechsolutions.org/vials.htm
