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.
