Precision Glass for Laboratory Instruments – custom precision glass machined to drawing with inspection reports. No minimum order; DFM review included with every RFQ.
What precision glass for laboratory instruments actually buys from a glass shop: cuvettes, sight glasses, stir-cell windows. The requirement underneath is chemically durable cells and windows in small lots.

Design guidance
The shop-floor rules that matter here:
- 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.
Where these parts end up
The recurring buyers of precision glass for laboratory instruments: microfluidic devices (chips, manifolds, via plates, bonded stacks); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); laser systems (windows, beam splitters, debris shields).
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
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 do laboratory instruments programs usually order?
Cuvettes, sight glasses, stir-cell windows. Typical spec: hydrolytic class 1 materials, fast-turn prototypes.
