Borosilicate Glass Capillary Tube

Goodfellow offers a range of borosilicate glass capillary tubes ideal for scientific and industrial applications. Borosilicate glass is known for its very low thermal expansion coefficient, high heat resistance, and high chemical durability. The non-porous glass prevents gas permeation, while the tubular shape allows for precision fluid control. Common uses include laboratory sample handling, microfluidics, capillary chromatography, and fabrication of gas laser discharge tubes. With diameters from 0.1 mm to 3 mm, these precision-drawn borosilicate glass tubes from Goodfellow enable experiments across a range of scales.
