Compare Starna Scientific cuvettes with scuvette JGS1 fused-silica cells. Spec table, Starna 1-Q / 21-Q / 23-Q cross-reference, pricing and delivery. Factory-direct price, 1–3 day dispatch, worldwide shipping.
Starna Scientific (Essex, UK, est. 1964) is a respected name in high-precision cells and certified reference materials. When labs consider switching, it is usually for one of these reasons:
| Specification | Starna | scuvette JGS1 | Notes |
|---|---|---|---|
| Quartz material | Spectrosil (synthetic fused silica) | JGS1 fused silica (Japanese imported) | Both are synthetic fused quartz; equivalent purity. |
| UV cut-off | 170 nm | 190 nm | Both suitable for deep-UV work. |
| NIR upper limit | 2700 nm | 2500 nm | Full UV-VIS-NIR coverage. |
| Path length tolerance | ±0.01 mm | ±0.01 mm | Critical for Beer-Lambert accuracy. |
| Dimensional tolerance | ±0.1 mm | ±0.05–0.1 mm | Instrument holder fit. |
| Parallelism of optical faces | <0.02° | <0.02° | Prevents beam-deflection artifacts. |
| Surface flatness | λ/4 per inch | λ/4 per inch | Keeps stray light low. |
| Transmittance | >88% (250 nm) | >80% (paired testing) | Brand-grade Q/QS levels exceed 90%. |
| Working temperature | Up to ~1000 °C | <100 °C (glued cells) | Sintered/one-piece cells available for high-temp. |
| Chemical resistance | Neutral & solvent (varies by series) | Neutral samples (glued); custom sintered for solvents | Check solvent compatibility before switching. |
Both manufacturers use synthetic fused silica (not natural quartz). Our standard cells are made from Japanese-imported JGS1, transmitting 190–2500 nm — equivalent to the Spectrosil (synthetic fused silica) grades for UV-Vis and fluorescence measurements. Paired transmission test reports are included with every shipment.

scuvette cells follow the industry-standard 12.5 × 12.5 × 45 mm outline with 15 mm or 8.5 mm centre height, so they drop into holders made for Hellma/Starna/FireflySci/Thorlabs-dimensioned cells — including Agilent, Shimadzu, PerkinElmer, Thermo, Jasco and Hitachi instruments.

Switch to scuvette if you want:
scuvette operates under the ISO 9001 quality system with RoHS-compliant products. Raw material purity is batch-tested at SiO₂ ≥ 99.99% and reported with your order. We supplied cuvettes for China Space Station experiments and expedited production at short notice — earning an official letter of thanks from the Chinese Academy of Sciences. Certificates ship with every inquiry on request.
As the manufacturer, we accept custom orders the big brands often turn down or price out of reach: custom Z-height for legacy instruments, unusual window layouts, special closures, engraved markings, OEM packaging and private-label branding. Send a drawing or dimensions through our contact page and receive a quote within 1 business day.
For UV-Vis and fluorescence work, yes. JGS1 synthetic fused silica transmits 190–2500 nm, the same practical range as Spectrosil. We publish transmission data on request.
Yes. Every standard cell ships with paired-test transmission data, and we can supply matched sets (A–B pairs, quad sets) with the readings on the box.
Standard cells dispatch within 1–3 business days, and DHL/FedEx to the USA takes 3–7 business days. We can also arrange express dispatch on request.
Calibration reference materials are a separate Starna line. For cells and cuvettes we cover the full Starna geometry range, including IR and long-path cells.
