TOQUARTZ® solution
A pharmaceutical QC lab in New Jersey faced 7% absorbance deviation using generic cuvettes, leading to 3 failed FDA audits in 2022. After switching to TOQUARTZ® cuvettes, deviation dropped to 1.2%, enabling consistent IR identity testing of APIs and reducing retest costs by $4,800 per batch.
Quartz Infrared Micro Cuvette in Polymer and Plastics Material Analysis
Key Advantages
-
1mm pathlength option minimizes IR saturation in high-absorbance polymer blends
→ Enables accurate peak resolution in carbonyl and amide regions. -
Surface roughness Ra ≤ 0.01μm reduces IR scattering in opaque samples
→ Improves signal-to-noise ratio by up to 25% in FTIR spectra. -
Thermal shock resistance up to 200°C/min prevents cuvette cracking during hot melt testing
→ Supports direct analysis of molten polymers without pre-cooling.
TOQUARTZ® solution
A Japanese polyamide manufacturer reported 18% signal distortion using standard cuvettes for FTIR additive analysis. TOQUARTZ® cuvettes with 1mm pathlength and ultra-smooth surfaces reduced distortion to under 3%, enabling accurate quantification of stabilizers and reducing QC rejection rate by 12%.
Quartz Infrared Micro Cuvette in Environmental Water Testing
Key Advantages
-
Background absorbance <0.2% at 3400cm⁻¹ ensures clean baselines for trace detection
→ Enhances detection sensitivity for hydrocarbons and nitrates. -
Certified non-leaching adhesive prevents contamination in low-concentration samples
→ Maintains sample integrity in ppb-level pesticide analysis. -
Matched pair ΔT < 0.5% at 1720cm⁻¹ improves signal reproducibility in dual-beam FTIR
→ Reduces false positives in regulatory water testing protocols.
TOQUARTZ® solution
An environmental lab in Ontario failed to detect 0.5ppm benzene due to cuvette background interference. After adopting TOQUARTZ® cuvettes, baseline noise dropped by 38%, enabling accurate detection at 0.2ppm and meeting EPA Method 418.1 compliance with zero retests in 6 months.

Usage Guide of Quartz Infrared Micro Cuvette
Handling and Sample Loading
- Always handle cuvettes by the non-optical sides to avoid fingerprints on measurement surfaces
- Fill slowly to prevent air bubble formation, which can interfere with measurements
- Maintain minimum 80% fill volume for accurate pathlength consistency
- Use appropriate micropipettes for precise volume delivery
- Allow temperature equilibration before measurement for highest accuracy
Cleaning and Maintenance
- Rinse with distilled water immediately after use
- For thorough cleaning, use mild detergent solutions (pH 6-8)
- Avoid abrasive materials that can scratch optical surfaces
- Rinse multiple times with distilled water to remove all cleaning agents
- Dry with clean, compressed air or nitrogen to prevent water spots
- Store in original protective packaging when not in use
Compatibility Considerations
- Suitable for neutral aqueous solutions and buffers (pH 6-8)
- Not recommended for strong acids, alkalis, or organic solvents
- Adhesive bonded areas should not contact aggressive chemicals
- Maximum operating temperature: 80°C (for bonded cuvettes)
- Prevent rapid temperature changes that may cause thermal stress

FAQ
Q: Are TOQUARTZ Quartz Infrared Micro Cuvettes compatible with FTIR instruments?
A: Yes, our cuvettes are designed to be compatible with most FTIR spectrophotometers. The standard dimensions (12.5 x 12.5 x 45 mm) fit common instrument holders, but we also offer custom dimensions to match specific instrument requirements. Please provide your instrument model when ordering for optimal compatibility.
Q: What is the certified material purity of the quartz used in these cuvettes?
A: TOQUARTZ® cuvettes are made from synthetic quartz with a certified purity of ≥99.98% SiO₂, and selected models reach up to 99.995% purity, verified by third-party material analysis.
Q: What is the actual transmittance range of the cuvettes across the IR spectrum?
A: Each cuvette pair is tested to ensure >80% transmittance between 260nm and 3500nm, with no absorption peaks in the mid-IR region (especially 2800–3000cm⁻¹).
Q: What is the maximum allowable deviation in pathlength for custom orders?
A: For custom pathlengths (1mm–5mm), we maintain a maximum deviation of ±0.05mm for critical applications, with full dimensional verification included in the QC report.
Q: How should I clean my Quartz Infrared Micro Cuvette to maintain optical clarity?
A: For routine cleaning, rinse with distilled water immediately after use, followed by a gentle rinse with a mild detergent solution if necessary. Avoid abrasive materials and harsh chemicals. After cleaning, rinse thoroughly with distilled water and dry with clean, compressed air or nitrogen. For persistent residues, specialized optical cleaning solutions can be used.
