Quartz glass rods

In addition to quartz glass tubes, Raesch Quarz (Germany) GmbH also produces quartz glass rods in various high-purity material qualities and properties.

Our quartz glass rods are available with outer diameters from 10 mm to 50 mm and a max. length of approx. 3,000 mm, available in five material specifications.

Upon customer request, we also take over the finishing or further processing of rods.

Using our state-of-the-art vacuum annealing process, the OH content can be adjusted to <5ppm for improved response and thermal stability.
