Our micro capillaries and tubes are manufactured for an international clientele from patented thermometer glass I-860: the alkali-lime glass is extremely resistant to ageing. It is certified by the Physikalisch-Technischen Bundesanstalt (federal physical-technical institute) for temperatures up to 350°C and belongs to the third hydrolytic class.

In production our glass tubes and capillaries are drawn via three newly developed Vello feeders. This gives a low degree of sagging and gives our tubing lower tolerances in outer diameters and wall thicknesses. The process gives us flexibility in our range of products and allows us to carry out your orders swiftly.
