Quality glass capillaries for microinjection and microelelctrodes. Also used for patch clamp fluid handling.

• Large variety available
• Some varieties of fire polished capillary glass
• OD/ID Tolerance: ±0.1 mm
• Length Tolerance: ±1 mm

Recommended to use with glass handling forceps.

Fire-polished glass capillaries are easier to insert into microelectrode holders without damaging the gasket. More importantly, fire-polished glass capillaries 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 dimensional tolerances assure microelectrode uniformity and reproducibility. Glass capillaries are available in 1, 2, 3, 5 and 7 barrel configurations, complete range of single barrel thinwall sizes and a variety of special configurations. Glass capillaries with filaments contain a solid filament fused to the inner wall, which speeds filling of electrodes. Glass capillaries with or without inner filaments are available for making microelectrodes in a wide range of diameters.

Single barrel standard wall thickness glass capillaries are offered either with or without inner filaments for quick filling in a variety of lengths and diameters. Thin wall single barrel glass capillaries are offered both with or without inner filaments.

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