These capillaries are intended for single use only. They automatically fill themselves right from one end to the other. Their accuracy is better than 1%. A capillary holder is provided with each pack of these capillaries. This holder consists of the guide for the capillary and a small bulb with an opening which must be mounted on the capillary. Pressing on this bulb is an effective means for assisting filling and emtying of the capillary.
