Compare Hellma QS cuvettes with scuvette JGS1 fused-silica cells. Spec-by-spec table, Hellma 100-QS / 101-QS / 104-QS cross-reference, pricing and delivery. Factory-direct price, 1–3 day dispatch, worldwide shipping.
Hellma Analytics is the most recognisable name in precision quartz cuvettes — and usually the most expensive. Typical pain points we hear from labs that switch:
| Specification | Hellma | scuvette JGS1 | Notes |
|---|---|---|---|
| Quartz material | Suprasil® (Heraeus) | JGS1 fused silica (Japanese imported) | Both are synthetic fused quartz; equivalent purity. |
| UV cut-off | 170–185 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 Suprasil® (Heraeus) 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.
Both are synthetic fused silica. Our standard line uses Japanese-imported JGS1, which covers 190–2500 nm — equivalent transmission range to Suprasil for routine UV-Vis and fluorescence work. We publish paired transmission test data on request.
We are the factory. There is no distributor chain — no Hellma-to-VWR-to-lab markup. Same raw quartz class, direct pricing.
Standard cells use the 12.5 × 12.5 × 45 mm outline and 15 mm (or 8.5 mm) centre height that match Hellma-dimensioned holders. Send us your instrument model or part number and we will confirm fit before you order.
Yes — we can supply sintered and one-piece moulded cells for solvents, acids and temperatures above 100 °C. Ask for the sintered option on custom orders.
We focus on cuvettes and cells; Hellma also sells certified reference standards, which are a separate product line. For cells alone, scuvette covers the full Hellma geometry range.
