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.

Getting the drawing right
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.
Capabilities and limits
One material, many routes: on D263 Thin Glass we also quote drilling, cnc machining, etching, polishing, and multi-step drawings are the norm rather than the exception.
Where these parts end up
The recurring buyers of d263 thin glass for microfluidic devices: microfluidic devices (chips, manifolds, via plates, bonded stacks); oled packaging (cover lids, frit-seal frames, fill-port plates); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows). Background reading on the underlying material science: SCHOTT D 263 thin glass.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.
Engineers scoping this work usually also review custom microfluidic chip, microfluidic glass applications, laser glass cutting.
Common questions
How does D263 Thin Glass behave under heat?
CTE is 7.2 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where down-drawn fire-polished surfaces matters.
What do microfluidic devices programs usually order?
Chips, manifolds, via plates, bonded stacks. Typical spec: channels from 10 um, bond voids < 1%.
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.
