Glass-on-Glass Microfluidic Chips – fusion bonded at 600+ C, no adhesives in channels. No minimum order; DFM review included with every RFQ.
Every chip project starts with a channel layout. Send DXF or GDSII and glass-on-glass microfluidic chips come back as quoted geometry – fusion bonded at 600+ C, no adhesives in channels.
Specification envelope

Design guidance
The shop-floor rules that matter here:
- Channel cross-sections are process-specific: etched channels are lens-shaped, machined ones rectangular with corner radii. State which your CFD model assumed.
- 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.
Who orders this
The recurring buyers of glass-on-glass microfluidic chips: laboratory instruments (cuvettes, sight glasses, stir-cell windows); microfluidic devices (chips, manifolds, via plates, bonded stacks); scientific instruments (reference flats, cells, prism mounts, stage inserts).
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.

Frequently asked questions
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.
Is there a minimum order for glass-on-glass microfluidic chips?
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.
