Oval capillaries

Oval capillaries with thin walls are also manufactured using our special redrawing technique for profile tubes. Very thin wall thicknesses from 0.1 mm to 0.4 mm can be achieved with direct forming. The oval form can take a number of different geometric shapes, meaning it is possible to create width-to-height ratios of varying degrees.

Materials

• Soda-lime glass (e.g. AR^©)
• Borosilicate glass (e.g. DURAN^©, PYREX^©, SIMAX^©)
• Neutral glass (e.g. FIOLAX^© and DUROBAX^©)
• Aluminum-silicate glass (e.g. Schott 8252/8253)
