Quartz Glass Glass Tubes – Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); OD 3 – 200 mm, cut length +/-0.1 mm. No minimum order; DFM review included with every RFQ.
quartz glass glass tubes are ordered for flow cells, sight glasses and furnace liners. The geometry envelope is OD 3 – 200 mm, cut length +/-0.1 mm, held to end squareness 0.05 mm, in Quartz Glass.

Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
- Hold the controlling dimension (end squareness 0.05 mm) and let secondary dimensions carry standard tolerance – it is the single biggest cost lever.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Manufacturing capability
One material, many routes: on Quartz Glass we also quote coring, edge grinding, cnc machining, drilling, and multi-step drawings are the norm rather than the exception.
Production route: cnc machining, grinding, drilling – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Who orders this

Common questions
Is there a minimum order for quartz glass glass tubes?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
