Narishige's GD-2 glass capillary tubing are special borosilicate glass capillary tubes, 90 mm in length, and have been pre-washed in an ultrasonic bath. Each capillary has a glass filament (approximate diameter of 100 µm) attached to the inner wall. The narrow interface between the circumferences of the fiber and the glass tube dramatically increases capillary action. This allows for easy back-filling of micro-capillary needles by simply inserting the back of the needle into a drop of liquid. Enhanced capillary action carries the liquid all the way to the needle tip in about one minute.
Outside Diameter = 2 mm
Inside Diameter = 1.2 mm
