Fused Silica Glass Wafers for Microfluidics – Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um). No minimum order; DFM review included with every RFQ.
What fused silica glass wafers for microfluidics actually buys from a glass shop: chips, manifolds, via plates, bonded stacks. The requirement underneath is optically clear, low-autofluorescence channel plates. Fused Silica is the fit here because it offers near-zero thermal expansion.

Getting the drawing right
The shop-floor rules that matter here:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- 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.
What the process holds
Beyond this page, Fused Silica routinely runs through lapping, dicing, etching, sandblasting in our shop – most real parts combine two or three of these steps.
Typical applications
fused silica glass wafers for microfluidics shows up across ccd inspection equipment (CCD cover plates, reference grids, stage glass); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports).

Frequently asked questions
Is there a minimum order for fused silica 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 Fused Silica parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Its hardness and brittleness demand diamond tooling and controlled feeds.
