Glass tubing as raw material
Not everything leaves here as a finished vessel. Tubing and semi-finished bodies are supplied to workshops that do their own forming.
01 / TUBING
H-32 borosilicate tubing
Drawn at our own plant in Japan and supplied by the length for further processing. Diameter and wall thickness to your specification.
02 / BLANKS
Blanks & semi-finished parts
Bodies already blown, annealed and dimensionally controlled, supplied for you to finish. See the 33 blank types →
03 / CONSISTENCY
One composition, one source
Because the material and the forming happen under one roof, composition and dimensional consistency stay the same from lot to lot over long programs.
