Usage Guide of Two Optical Windows Infrared Quartz Cuvette
Instruções de manuseio
- Always handle cuvettes by the non-optical sides or top edges to avoid fingerprints on optical windows.
- Use powder-free gloves when handling cuvettes to prevent contamination.
- Avoid dropping or applying mechanical stress to prevent micro-cracks that may affect optical performance.
- Allow cuvettes to gradually acclimate to temperature changes to prevent thermal shock.
Procedimentos de limpeza
- Rinse with appropriate solvent immediately after use to prevent sample residue from drying.
- For stubborn residues, soak in dilute laboratory detergent solution followed by thorough rinsing.
- For optical window cleaning, use spectroscopic-grade solvents and lint-free optical wipes.
- Air dry or use oil-free compressed air to remove dust particles before storage.
Recomendações de armazenamento
- Store in original protective case or dedicated cuvette holders to prevent dust accumulation and physical damage.
- Keep in a dry environment to prevent mineral deposits from forming on optical surfaces.
- For long-term storage, ensure cuvettes are thoroughly clean and completely dry.
Usage Tips
- Run baseline measurements before sample analysis to account for any cuvette-specific optical characteristics.
- For thermal applications, implement gradual temperature ramping to prevent thermal stress.
- Use matched pairs of cuvettes for differential measurements to minimize baseline variations.
- Maintain consistent orientation in instrument holders for reproducible measurements.

PERGUNTAS FREQUENTES
Q: Can quartz cuvettes be used for infrared spectroscopy?
A: Yes, TOQUARTZ® Two Optical Windows Infrared Quartz Cuvettes are specifically designed for infrared spectroscopy applications. Our high-purity fused quartz material offers excellent transmission in the 260nm-3500nm range, making it suitable for UV, visible, and infrared spectral analysis. The precision-ground optical windows ensure accurate and consistent measurements throughout the IR spectrum.
Q: What is the typical path length of an IR quartz cuvette?
A: The typical path lengths for Two Optical Windows Infrared Quartz Cuvettes range from 1mm to 50mm. Standard path lengths include 1mm, 2mm, 5mm, 10mm, 20mm, 30mm, 40mm, and 50mm. The selection depends on your sample’s concentration and absorption characteristics. For highly absorbing samples, shorter path lengths (1-5mm) are recommended, while dilute samples benefit from longer path lengths (10-50mm) to enhance sensitivity. TOQUARTZ® also offers custom path lengths to meet specific analytical requirements.
Q: What is the difference between quartz and glass cuvettes for IR applications?
A: Quartz cuvettes offer superior infrared transmission compared to standard glass cuvettes. While glass typically absorbs infrared radiation above 2500nm, our Two Optical Windows Infrared Quartz Cuvettes transmit light up to 3500nm, allowing for a broader spectral analysis range. Quartz also provides better chemical resistance, higher temperature tolerance (up to 1100°C), and improved durability. These properties make quartz cuvettes essential for accurate infrared spectroscopy, especially when analyzing samples in aggressive solvents or at elevated temperatures.
Q: Can I use the same Two Optical Windows Infrared Quartz Cuvette for both UV and IR analysis?
A: Yes, TOQUARTZ® Two Optical Windows Infrared Quartz Cuvettes offer exceptional transparency across a wide spectrum from 260nm (UV) to 3500nm (mid-IR). This broad transmission range allows scientists to use a single cuvette for multiple spectroscopic techniques, including UV-Vis and FTIR, without changing sample containers. This multi-wavelength compatibility streamlines analytical workflows, reduces sample handling, and ensures consistent measurement conditions across different spectral regions.
Q: How do I clean an IR quartz cuvette?
A: Clean Two Optical Windows Infrared Quartz Cuvettes by first rinsing with an appropriate solvent compatible with your sample to remove residues. For thorough cleaning, use mild laboratory detergent solutions followed by multiple rinses with distilled water. For optical windows, use spectroscopic-grade solvents like acetone or methanol and lint-free optical wipes. Avoid abrasive materials that could scratch the optical surfaces. Always handle by the non-optical sides and allow to completely air dry before storage.
