Multi-Barrel Glass Capillaries Two-Barrel Multi-barrel configurations are designed especially for microiontophoresis. Because the capillaries are fused together during manufacture, you will not need to twist them while pulling to seal the tips together. An inner filament in each barrel makes filling easy and fast.

The natural bevel resulting from the prominent spear-like projection of the septum gives microelectrodes a sharp, spear-point tip. This style has low resistance for use as a single microelectrode, and it can be used to make superior double-tipped microelectrodes with low trans-tip coupling. The natural bevel of Septum Theta Septum Theta Piggyback also significantly increases the effective tip cross-section. As supplied, the width of the septum is approximately 0.2 mm; wall thickness is approxiSpecial Configuration Borosilicate Glass Tubing mately 0.2 mm.
