Quick answer: D263 Thin Glass Glass Wafers for Microfluidics covers D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um). Prototypes ship in 5-10 working days.
d263 thin glass glass wafers for microfluidics programs need optically clear, low-autofluorescence channel plates. D263 Thin Glass is the fit here because it offers down-drawn fire-polished surfaces. Typical parts: chips, manifolds, via plates, bonded stacks.

Process window
Beyond this page, D263 Thin Glass routinely runs through edge grinding, etching, grinding, double-side polishing in our shop – most real parts combine two or three of these steps.
DFM notes from the shop floor
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.
The full rules live in our tolerance design guide and holes and edges design guide.
Typical applications

Frequently asked questions
Is there a minimum order for d263 thin glass glass wafers for microfluidics?
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.
What tolerances are achievable on D263 Thin Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
