Cheap glass plates for ABI automated sequencer

[bb1dopeg]

Hi there,

Glass plates for 373A, 373Stretch or 377 DNA sequencers from
Perkin-Elmer/AppliedBiosystems are extremely expensive. Unfortunately,
cheap standard glass plates cannot be used because they produce too
high background fluorescence...

I wonder if anyone knows where to buy "clean" glass plates at a
"decent" price.

Many thanks in advance.
