Capillary tubing, or microtubing, exhibits capillary action. Capillary action is the movement of a liquid into a capillaries based on its surface tension. These microtubes are used in liquid measurement, liquid transfer and sample collection applications, Gas Chromatography, Capillary Liquid Chromatography, Capillary Electrophoresis, and Raman spectroscopy. Typical industries served are Analytical, Medical, Aerospace, Military, Industrial, Telecommunication and Communication.

Micro tubes manufactured to customer specifications:
