High Precision Borosilicate Glass Tubes
We offer high precision borosilicate glass capillary tubes, with different size of inner diameter holes. Based on fiber drawing technology, we can achieve various geometric sizes and specifications of precision circular glass capillaries. With CNC machine tools for batch cutting, after strict annealing and end face precision grinding processes, precision circular glass tubes and special-shaped glass tube products are obtained.
