Fabricate two-barrel electrodes

Piggyback glass capillaries consist of a pair of borosilicate capillaries fused together during manufacture. One barrel is larger than the other, and both have inner filaments for quick filling. Piggyback glass makes it simple to fabricate two-barrel electrodes with a significant tip diameter differential.
