Usage Guide of UV-Grade Dual-Path Quartz Cuvette
Handling & Cleaning
- Always handle cuvettes with clean gloves to prevent fingerprints on optical surfaces.
- Clean with mild detergent (pH 7-8) followed by thorough rinsing with distilled water.
- For organic residues, use spectroscopic-grade solvents (acetone, ethanol) followed by water rinse.
- Avoid abrasive materials or brushes that could scratch optical surfaces.
- Dry with clean, compressed air or nitrogen rather than wiping.
Storage & Maintenance
- Store in the original protective case or in a dust-free environment.
- Avoid rapid temperature changes that could cause thermal stress.
- Inspect regularly for chips, cracks, or surface contamination.
- For long-term storage, ensure cuvettes are thoroughly clean and dry.
- Maintain an inventory record including usage history and cleaning cycles.
Sample Loading & Measurement
- Fill to the recommended volume to ensure proper light path alignment.
- Avoid air bubbles by tilting the cuvette slightly during filling.
- Clean optical windows with lens tissue before placement in instrument.
- Ensure correct orientation with light path perpendicular to the beam.
- For paired cuvettes, maintain consistent orientation between reference and sample.
Chemical Compatibility
- Compatible with most acids, bases, and organic solvents (except HF).
- Avoid prolonged exposure to concentrated alkaline solutions above pH 12.
- Rinse immediately after use with corrosive or reactive samples.
- For samples containing fluoride compounds, limit exposure time and rinse thoroughly.
- For unusual or highly reactive samples, test compatibility on a spare cuvette first.

FAQ
Q: What are the standard path lengths available for UV-Grade Dual-Path Quartz Cuvettes?
A: TOQUARTZ® standard path lengths include 1mm, 2mm, 5mm, 10mm, 20mm, 50mm, and 100mm. The most commonly used path length is 10mm, which is compatible with most spectrophotometers. We also offer custom path lengths between 0.5mm and 100mm to meet specific application requirements. All path lengths are manufactured with a tolerance of ±0.01mm to ensure measurement accuracy.
Q: How should I clean UV-Grade Dual-Path Quartz Cuvettes to maintain optical performance?
A: For routine cleaning, we recommend using a mild detergent solution (pH 7-8) followed by thorough rinsing with distilled or deionized water. For more stubborn residues, spectroscopic-grade solvents like acetone or ethanol can be used, followed by water rinsing. Always avoid abrasive materials or brushes that could scratch the optical surfaces. Dry with clean, compressed air or nitrogen rather than wiping. For detailed cleaning protocols for specific sample types, please refer to our complete usage guide.
Q: What is the temperature resistance of your UV-Grade Dual-Path Quartz Cuvettes?
A: TOQUARTZ® UV-Grade Dual-Path Quartz Cuvettes can withstand temperatures up to 1100°C, making them suitable for high-temperature applications. However, we recommend not exceeding 600°C for standard designs to avoid potential stress on seams or joints. For rapid temperature changes, we suggest limiting the rate to 10°C/minute to prevent thermal shock. For applications requiring extreme temperature cycling or exposure above 600°C, please consult with our engineering team for specially designed high-temperature versions.
Q: Can TOQUARTZ® provide UV-Grade Dual-Path Quartz Cuvette with certified optical flatness?
A: Yes, we offer optical surface flatness certification up to ≤λ/4, verified using Zygo interferometers for high-precision applications.
Q: Are your UV-Grade Dual-Path Quartz Cuvette tested for birefringence or internal stress?
A: Yes, we conduct birefringence testing using polarized light to ensure internal stress is below 10nm/cm, critical for high-precision optical systems.
