new capillary cross-section

Twisted capillaries

Twisted glass capillaries can be manufactured with various gradients and widths. The inner diameters and the geometries of these capillaries are basically created by mechanical hot forming. Thereby a rotating round tube is twisted specifically in itself.

Materials

• Soda-lime glass (e.g. AR©)
• Borosilicate glass (e.g. DURAN©, PYREX©, SIMAX©)

Process of Production
