TOQUARTZ® Solving Challenges with Quartz Cuvette with
Two Optical Windows
Quartz Cuvette with Two Optical Windows for Research Laboratories
Key Advantages
-
Matched path length deviation within ±0.05mm
Ensures experimental repeatability in UV-Vis assays requiring <2% absorbance variance. -
Verified transmission >83% at 200nm (paired cuvettes)
Supports nucleic acid quantification with minimal baseline drift in UV range. -
Batch-to-batch optical deviation <1.2% (internal QC data, 2024 Q4)
Reduces inter-batch calibration errors in long-term research projects.
TOQUARTZ® solution
A German university research lab conducting protein-ligand binding studies reported 12% absorbance deviation using generic cuvettes. After switching to TOQUARTZ® matched-pair cuvettes (±0.05mm tolerance, >83% UV transmission), their standard deviation dropped to 2.1% across 30 replicates. This improved data reliability and reduced experiment reruns by 40%, saving over €3,000 in reagent costs per quarter.
Quartz Cuvette with Two Optical Windows for OEM Instrument Manufacturers

TOQUARTZ® solution
A U.S.-based spectrophotometer OEM faced recurring delays due to inconsistent cuvette supply, causing 8–10 day production halts quarterly. TOQUARTZ® implemented a rolling forecast inventory model and delivered 96% of orders within 24 hours. Over 12 months, the OEM reduced line stoppages by 87% and improved on-time delivery rate from 82% to 98.5%, directly impacting customer satisfaction scores.
Quartz Cuvette with Two Optical Windows for Medical Diagnostics
Key Advantages
-
Custom path lengths from 5mm to 90mm with ±0.05mm tolerance
Enables integration into compact diagnostic cartridges with strict spatial constraints. -
Optical clarity >90% @220–800nm (validated by UV-Vis scan)

Accelerates IVD device development cycles and regulatory testing.
TOQUARTZ® solution
A Japanese IVD startup developing a point-of-care CRP test required a 45mm cuvette with non-standard wall thickness and tight optical specs. Their previous supplier quoted 6–8 weeks. TOQUARTZ® delivered prototypes in 12 working days and full batch in 3 weeks. This enabled the client to complete clinical validation 5 weeks ahead of schedule, securing a ¥12M government grant for early commercialization.

Usage Guide of Quartz Cuvette with Two Optical Windows
Handling and Measurement
- Always handle cuvettes by the non-optical sides to prevent fingerprints on optical windows.
- Verify optical path alignment by ensuring optical windows are perpendicular to light path.
- Allow temperature equilibration between sample and cuvette before measurement.
- Maintain consistent filling volumes for reproducible results.
Cleaning and Storage
- Rinse with appropriate solvent immediately after use to prevent sample residue.
- For thorough cleaning, use mild detergent solution followed by deionized water rinse.
- Air dry in dust-free environment or use compressed air (oil-free).
- Store in original protective case at room temperature away from chemicals.
Important Notes:
- Avoid abrasive cleaning materials that can scratch optical surfaces.
- Never subject cuvettes to rapid temperature changes which can cause thermal stress.
- For fluoride-containing solutions, limit exposure time to prevent surface etching.

FAQ
Q: What is the chemical resistance of your quartz cuvettes?
A: TOQUARTZ® quartz cuvettes with two optical windows offer exceptional chemical resistance to most acids, bases, and organic solvents. They are stable with most chemicals except hydrofluoric acid (HF) and hot phosphoric acid. For long-term exposure to strong alkaline solutions (pH>12), we recommend consulting our technical team for specific guidance.
Q: Are the two optical windows on the quartz cuvette optically matched for paired measurements?
A: Yes, each pair of TOQUARTZ® cuvettes is optically matched with transmission deviation less than 1.2% at 200nm, ensuring consistent absorbance readings in dual-beam spectrophotometers.
Q: Can TOQUARTZ® two-window quartz cuvettes be used with automated sample changers?
A: Yes, our cuvettes are compatible with most automated UV-Vis systems; we also offer custom outer dimensions to fit specific robotic arms or tray systems.
Q: Do the optical windows have anti-reflective or hydrophobic coatings?
A: No coatings are applied by default to preserve UV transparency; however, we offer optional surface treatments such as hydrophobic coating or AR coating upon custom request.
Q: Can you provide optical transmission data for your quartz cuvettes?
A: Yes, we provide optical transmission curves for our quartz cuvettes upon request. Our standard two-path quartz cuvettes typically show >80% transmission at 200nm and >90% across 220-2500nm wavelength range. For critical applications, we can provide batch-specific transmission data verified through our optical testing laboratory.
