D263 Thin Glass for Microfluidic Devices: D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um). Single-piece prototypes to production volumes, quoted from your drawing.
What d263 thin glass for microfluidic devices actually buys from a glass shop: chips, manifolds, via plates, bonded stacks. The requirement underneath is optically clear, low-autofluorescence channel plates. D263 Thin Glass is the fit here because it offers down-drawn fire-polished surfaces.

Specification advice
The shop-floor rules that matter here:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- 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 D263 Thin Glass we also quote grinding, cnc machining, polishing, dicing, and multi-step drawings are the norm rather than the exception.
Who orders this
d263 thin glass for microfluidic devices shows up across oled packaging (cover lids, frit-seal frames, fill-port plates); led packaging (groove covers, phosphor carriers, package windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Common questions
Is there a minimum order for d263 thin glass for microfluidic devices?
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.
