Quartz Laboratory Glassware and Apparatus
When laboratory work involves temperatures, UV light or chemicals that destroy borosilicate glassware, fused quartz is the material of choice. Quartz labware withstands continuous use around 1100 °C, transmits UV light down to wavelengths ordinary glass blocks, and resists nearly all acids.
Typical Laboratory Uses
- High-temperature work — crucibles, combustion tubes, boats for ashing, calcination and fusion procedures.
- UV applications — cuvettes and flow cells for UV spectrophotometry, photochemistry reactors.
- Trace analysis — high-purity quartz vessels minimize background contamination in sensitive analytical chemistry.
- Custom apparatus — one-off glassblown assemblies built from a sketch or description.
Quartz vs Borosilicate for Labware
| Requirement | Borosilicate | Fused Quartz |
|---|---|---|
| Continuous use temperature | ~230–250 °C thermal shock limit; lower continuous ratings | ~1100 °C continuous |
| UV transmission below 300 nm | Poor | Excellent (grade dependent) |
| Acid resistance | Good | Excellent (except HF) |
| Relative cost | Lower | Higher |
If your procedure stays below a few hundred degrees and needs no UV, borosilicate is usually enough. When it does not survive, quartz is the upgrade.
Custom Laboratory Quartz
Much lab quartz is custom: specific neck geometries, ground joints, fritted elements or unusual assemblies. We fabricate custom apparatus from drawings and sketches — send us your requirement for review.
