Fire Polishing
Fire-Polished glass capillaries are easier to insert into microelectrode holders without damaging the gasket. More importantly, fire-polished glass won’t scratch the chloridized wire used in a recording electrode. Fire-polishing does not affect the glass’s mechanical or electrical properties.
Making Uniform, Reproducible Microelectrodes
Borosilicate glass capillaries: Close dimensional tolerances assure microelectrode uniformity and reproducibility. Capillaries are available in 1, 2, 3, 5 and 7-barrel configurations, complete range of single barrel thin-wall sizes and a variety of special configurations. Capillaries with filaments contain a solid filament fused to the inner wall, which speeds filling of electrodes. Capillaries with or without inner filaments are available for making microelectrodes in a wide range of diameters.
Filament Glass Capillaries
Single Barrel standard wall thickness capillaries are offered either with or without inner filaments for quick filling in a variety of lengths and diameters.
Thin Wall Glass Capillaries
Thin Wall single barrel capillaries are offered both with or without inner filaments.
NOTE: Because electrode tips erode when left filled with saline solutions for long periods, electrodes should be made and filled immediately prior to use.
