Polymer Capillary Tubing

Polymer Capillary Tubing

Enabling the Vision of Tomorrow Through Custom Microfluidic Handling

Incom’s polymer capillary tubing is available in many different sizes with many different types of materials. Custom medical grade capillary tubes are also available and are manufactured from medical grade materials using a cleanroom-enclosed fiber optic draw tower. Incom’s unique manufacturing technique allows for a wide range of inside and outside dimensions and significantly smaller sizes, than what is typically available commercially, with OD’s as small as 25μm.

The capillaries can be made in either single and multi-hole designs with unique patterns and shapes, to satisfy your specific needs. Their process is scalable and fully customizable to meet your individual requirements.
