Precision glass tubes
As a special feature, we also offer glass tubes and cylinders that have been internally calibrated. An internal tool is used here to shape these tubes and cylinders into their exact dimensions and preferred form. The standard round form is possible, however square or conical are other options. Cylindrical grinding can also be used to externally calibrate the tubes. The grinding also leaves the surface with a frosted finish. Finishing touches are then added with the final “technical polishing”.
