Physical Properties of WPI Glass Capillaries
The physical properties of glass depend upon the chemical composition of the glass, as well as how the glass was manufactured. Glass has no set melting point, but four temperatures are of primary importance when discussing glass production.

Buying Multi-Barrel Glass Capillaries
Two-barrel, 3-barrel, 5-barrel and 7-barrel glass capillaries are available at WPI. Multi-barrel configurations are designed especially for microiontophoresis. Because the capillaries are fused together during manufacturing, 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.
