The Biopsy Channel White three-layer tubing is a high-tech composite medical tubing.
Using precise three-layer co-extrusion technology, it combines polymers with different properties and is specifically designed for manufacturing the biopsy working channel of endoscopes.
It achieves the optimal balance of “smoothness,” “support,” and “flexibility.”
