How to Clean IR Quartz Cuvettes & Maintenance Guide
How to Clean IR Quartz Cuvettes
- Rinse with distilled water immediately after use
- For organic contaminants, use a 1:2 mixture of hydrochloric acid and ethanol
- For oil-based residues, rinse with petroleum ether
- For stubborn contaminants, specialized ultrasonic cleaning with the frosted side facing down is recommended
- Final rinse should be with distilled water (3x) followed by air drying
- Never use: alkaline solutions, abrasive materials, hard brushes, or fluoride-containing solutions
Proper Handling Techniques
- Always handle cuvettes by the frosted or non-optical sides
- Avoid touching optical windows to prevent fingerprints and contamination
- Use appropriate cuvette holders to prevent dropping or mechanical stress
- Allow samples to reach ambient temperature before placing in cuvettes to prevent thermal shock
- When inserting into instruments, ensure proper alignment with light path
IR Quartz Cuvette Solvent Compatibility
- Compatible with most organic solvents including acetone, methanol, ethanol, and hexane
- Compatible with most aqueous solutions and dilute acids
- Compatible with dilute bases (short exposure recommended)
- For uncertain compatibility, conduct small-scale tests or contact our technical support
- Incompatible with: hydrofluoric acid (HF), concentrated fluoride solutions, and long-term exposure to strong bases
Storage Recommendations
- Store clean, dry cuvettes in original protective case
- Keep in dust-free environment at room temperature
- Avoid direct sunlight and humidity

FAQ
Q: What is the wavelength range of your IR quartz cuvettes?
A: TOQUARTZ® IR quartz cuvettes offer transmission across a spectral range from 260nm to 3500nm, covering UV, visible, and infrared regions. This makes them suitable for both UV and IR spectroscopy applications without the need for different materials.
Q: How do I clean IR quartz cuvettes without damaging them?
A: Clean IR quartz cuvettes by first rinsing with distilled water immediately after use. For organic contaminants, use a 1:2 mixture of hydrochloric acid and ethanol. For oil-based residues, rinse with petroleum ether. Always finish with three rinses of distilled water and air dry. Never use alkaline solutions, abrasive materials, or hard brushes. For stubborn contaminants, ultrasonic cleaning with the frosted side facing down is recommended.
Q: What solvents are compatible with IR quartz cuvettes?
A: IR quartz cuvettes are compatible with most laboratory solvents including water, alcohols (methanol, ethanol), acetone, chloroform, hexane, toluene, most dilute acids, and short exposure to dilute bases. They are not compatible with hydrofluoric acid (HF), concentrated fluoride solutions, or prolonged exposure to strong alkaline solutions. For special applications, please consult our technical team.
Q:What is the temperature limit for IR quartz cuvettes?
A: TOQUARTZ® IR quartz cuvettes can withstand temperatures up to 1100°C, making them suitable for high-temperature applications. However, for sealed cuvettes, the temperature limit depends on the sealing material used. Standard sealed cuvettes typically have a temperature limit of 80-120°C. For higher temperature applications, special high-temperature seals can be provided.
Q: What is the path length tolerance of your IR quartz cuvettes?
A: TOQUARTZ® standard IR quartz cuvettes have a path length tolerance of ±0.01mm for path lengths under 10mm and ±0.1mm for longer path lengths. This precision ensures reliable quantitative analysis and reproducible results. Custom path lengths with specific tolerances are available upon request.
