Bonded Glass Microfluidic Devices – fusion, anodic and adhesive bonding, voids < 1%. No minimum order; DFM review included with every RFQ.
Glass remains the reference material for microfluidics – solvent-proof, optically clean, and thermally stable. bonded glass microfluidic devices here are multi-layer sealed devices ready for tubing, with fusion, anodic and adhesive bonding, voids < 1%.

DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- 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 bonded glass microfluidic devices: led packaging (groove covers, phosphor carriers, package windows); oled packaging (cover lids, frit-seal frames, fill-port plates); 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.

Common questions
Is there a minimum order for bonded glass 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.
