TOQUARTZ® Advanced Solutions for Precision Spectroscopy Applications with Quartz Fluorescence Reaction Cuvettes
Quartz Fluorescence Reaction Cuvette in Photodynamic Therapy (PDT) Drug Screening
Key Advantages
-
Oxygen-Blocking Screw Cap Design
Maintains oxygen levels below 0.5 ppm during 30-minute irradiation cycles. -
UV-Resistant Quartz Surface Stability
No surface degradation after 50+ exposures to 630nm laser at 100 mW/cm². -
pH-Neutral Optical Chamber
Internal surface pH shift <0.1 after 24h exposure to porphyrin-based photosensitizers.
TOQUARTZ® solution
A Canadian PDT research lab observed 18–22% fluorescence signal loss due to oxygen quenching and photobleaching in open-top cuvettes. After switching to TOQUARTZ® sealed quartz cuvettes, quantum yield measurements stabilized within ±2%, and photobleaching was reduced by 35% over 40-minute light exposure. This enabled accurate evaluation of 7 new photosensitizer candidates under ISO 10993-5 protocols.
Quartz Fluorescence Reaction Cuvette in Food Safety Fluorescence Detection
Key Advantages
-
Ethanol-Resistant Quartz Integrity
No surface etching after 100 cycles of 70% ethanol-based aflatoxin extraction. -
Low-Autofluorescence Baseline (<0.002 AU)
Background signal at 365nm excitation measured 0.0018 AU in blank runs. -
Sealed Cap Prevents Volatile Loss
Maintains aflatoxin B1 concentration within ±1.5% over 2-hour batch testing.
TOQUARTZ® solution
A Polish food safety lab testing aflatoxins in corn extracts reported 12% false positive rate due to cuvette autofluorescence and ethanol-induced degradation. After adopting TOQUARTZ® cuvettes, background signal dropped by 87%, and retest frequency decreased by 40%. This improved compliance with EU Regulation No. 1881/2006 for aflatoxin B1 limits (2 μg/kg).
Quartz Fluorescence Reaction Cuvette in Forensic Trace Evidence Fluorescence Analysis
Key Advantages
-
Micro-Volume Compatibility (≤200μL)
Enables trace analysis with sample volumes as low as 150μL without signal loss. -
Four-Sided Optical Clarity (≥92% at 450nm)

Leak-Proof Seal for Volatile Traces
Prevents evaporation of ethanol-based dye residues for up to 4 hours at 25°C.
TOQUARTZ® solution
A forensic lab in Germany analyzing dyed synthetic fibers encountered 30% signal variability due to cuvette wall scattering and sample evaporation. TOQUARTZ® cuvettes with four-sided optical polishing and screw caps improved signal-to-noise ratio by 35% and preserved sample integrity for extended analysis.

Usage and Care Guidelines
Proper Handling & Cleaning
- Wear gloves: Always handle cuvettes with powder-free gloves to prevent fingerprints and contamination that can affect optical measurements.
- Initial cleaning: For new cuvettes, rinse with ultrapure water followed by spectroscopic-grade solvent compatible with your analysis.
- Routine cleaning: Empty cuvette immediately after use and rinse with appropriate solvent. For persistent residues, use 5% Hellmanex® solution or dilute acid (except HF).
- Drying: Allow to air dry in dust-free environment or use filtered compressed nitrogen gas for rapid drying.
- Avoid: Ultrasonic cleaners, abrasive materials, and hydrofluoric acid (HF), which attacks quartz.
Storage & Maintenance
- Storage container: Store in original protective case or dedicated dust-free container with soft lining to prevent scratches.
- Environmental conditions: Store in clean, dry environment away from chemical vapors that could contaminate optical surfaces.
- Regular inspection: Periodically check for chips, cracks, or scratches using appropriate light source.
- Thermal handling: Allow cuvettes to gradually reach operating temperature; avoid rapid temperature changes that can cause thermal shock.
- Cap maintenance: Inspect PTFE or quartz caps regularly for proper sealing. Replace if damaged to ensure proper containment.
Best Practices for Optimal Performance
- Validate optical performance periodically using certified reference materials to ensure measurement accuracy.
- Standardize handling procedures among laboratory personnel to minimize variation in results.
- Use dedicated cuvettes for specific applications to prevent cross-contamination between incompatible chemicals.
- Position cuvettes consistently in instrument holders to maintain reproducible optical path alignment.
- Consider maintaining a log of cuvette usage and cleaning history for critical applications.

FAQ
Q: Can the Quartz Fluorescence Reaction Cuvette be used with highly acidic or basic samples?
A: Yes, our cuvettes are chemically stable in pH 1–14 environments. The high-purity quartz resists corrosion from strong acids and bases, except hydrofluoric acid (HF), which should be strictly avoided.
Q: What is the autofluorescence level of the Quartz Fluorescence Reaction Cuvette under UV excitation?
A: The autofluorescence is <0.002 AU at 365nm excitation. This ensures minimal background interference in low-concentration fluorescence assays.
Q: How does the screw cap of the Quartz Fluorescence Reaction Cuvette improve sample integrity?
A: The precision screw cap prevents evaporation and contamination, especially for volatile solvents like ethanol or DMSO. It ensures consistent concentration during long assays.
Q: Can the Quartz Fluorescence Reaction Cuvette be used in field testing environments?
A: Yes, our cuvettes are compatible with portable fluorometers. The sealed design and chemical durability make them suitable for on-site environmental or food safety testing.
Q: How should the Quartz Fluorescence Reaction Cuvette be cleaned and stored to maintain performance?
A: Rinse with deionized water and spectroscopic-grade solvents. Avoid HF and ultrasonic cleaning. Store in a dust-free case to prevent scratches and contamination.
