Dear Kevin and other users,
The guys at do glass capillary arrays here
in the Bay Area. I hope this helps.

Hi Kevin,

One vendor I know is BURLE INDUSTRIES, INC, though I've never tried. They
routinely make glass capillary arrays with regular closely-spaced pores as
small as 2 um in diameter.  These arrays can be designed with variable
spacing and pore diameters.

Hope this helps.
