Manufacturer Borosilicate Glass Cleaning Procedure

Borosilicate glass capillaries: Close dimensional 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 .

Glass Configurations

THIN WALL SINGLE BARREL capillaries are offered both with or without inner filaments. The concentricity of this material provides excellent strength. Micropipettes made from thin wall capillaries have fine tips with a short taper. Thin wall capillaries without filaments do not have the Kwik-Fil feature.
SINGLE BARREL STANDARD wall thickness capillaries are offered either with or without inner filaments for quick filling in a variety of lengths and diameters. Two usable electrodes can be made from one 6-inch length. Capillaries without filaments do not have the Kwik-Fil feature.
MULTI-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.

Note: Because electrode tips erode when left filled with saline solutions for long periods, electrodes should be made and filled immediately prior to use.
