We Are the Factory Behind the Brand
Scuvette is a source factory, not a trading company. Since 2010 we have manufactured quartz cuvettes, sample cells, flow cells and optical laboratory consumables in our own facility in Yixing, Jiangsu, China — and sold them directly to laboratories worldwide. When you order from scuvette, there is no distributor, no reseller and no middleman markup between our workshop and your bench.
Tired of Paying 2–4× for the Same Quartz?
If you are buying quartz cuvettes through a laboratory supply catalogue, you are probably paying for three layers of markup — the brand, the distributor and the reseller — on a product that was made in a factory just like ours. Here is what buyers tell us they are tired of:
- "Same part number, 2–4× the factory price." A 10 mm quartz cell lists at $79–119 from premium brands; from the factory it is $35–45.
- "2–6 weeks lead time." When your instrument is down, waiting a month for a standard cell is unacceptable.
- "Nobody answers technical questions." Distributors sell boxes, not optical expertise.
- "Custom work is expensive or refused." Non-standard Z-height, unusual windows, OEM branding — big brands often say no.
- "High minimums." You should not have to buy 50 cells to get a fair price.
All of these problems disappear when you buy from the source.
What Buying Factory-Direct Means for You
| Pain point | Typical supply chain | Factory-direct (scuvette) |
|---|
| Price | Brand + distributor + reseller markup | 40–60% lower for the same JGS1 quartz |
| Lead time | 2–6 weeks (stock), 8–16 weeks (custom) | 1–3 day dispatch; custom 10–20 days |
| Support | Reseller without optical knowledge | Direct line to factory engineers |
| Custom & OEM | Often refused or expensive | Standard service — send a drawing, quote in 1 business day |
| Minimum order | Often 10–50 pcs | No minimum on standard cells |
| Quality data | Unavailable | Paired transmission reports included |
Quality You Can Verify
Being a factory means we can be fully transparent about what you are buying:
- Japanese-imported JGS1 synthetic fused silica — 190–2500 nm transmission, the same grade class as Suprasil/Spectrosil.
- Material purity report — SiO₂ content ≥ 99.99%, test report available with every batch.
- Paired transmission testing — every standard cell ships with measurement data; matched pairs and quad sets available.
- Documented fabrication — glued standard cells, plus sintered and one-piece options for solvents, acids and high-temperature work.
- Stated tolerances — path length ±0.01 mm, dimensional ±0.05–0.1 mm, parallelism <0.02°.
