WPI offers a wide spectrum of high-quality glass capillaries. We take pride in our ability to ship your glass order within 48 hours. If you need a special glass that does not appear in our catalog,please call us, We will make every effort to provide it for you.
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.
Borosilicate
glass capillaries:Close dimen-sional tolerances assure microelectrode
uniformity and reproducibility. Available in one-, two-, three-, five,-
and seven-barrel configurations; a 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.
Single
Barrel standard wall thickness capil-laries are offered either with or
without inner fila-ments for quick filling in a variety of lengths and
diameters. Two usable electrodes can be made from one 6-inch length.
Thin
Wall single barrel capillaries are offered both with or without inner
filaments. The concen-tricity of this material provides excellent
strength. Micropipettes made from thin wall capillaries have fine tips
with a short taper.
Note:Because
electrode tips erode when left filled with saline solutions for long
periods, electrodes should be made and filled immediately prior to use.
