Usage Guide of Fused Quartz Fluorescence Cuvette Cell
Handling & Storage Recommendations
- Always handle cuvettes by the frosted or non-optical sides to prevent fingerprints and contamination on optical surfaces.
- Store in original protective case when not in use to prevent scratches and dust accumulation.
- Inspect optical surfaces before use under proper lighting to ensure cleanliness.
- Allow sufficient equilibration time when changing between temperature environments to prevent thermal stress.
Quartz Cuvette Cleaning Procedure
- Rinse immediately after use with appropriate solvent compatible with your sample.
- For general cleaning, use ethanol-water (50:50) mixture followed by multiple rinses with distilled water.
- For organic contaminants, use ethanol-HCl mixture (2:1) followed by thorough distilled water rinses.
- For persistent contamination, specialized ultrasonic cleaning with cuvette oriented frosted side down for 10 minutes maximum.
- Air dry in vertical position on clean lint-free material or use filtered compressed air for drying.
Important Usage Considerations
Quartz Cuvette Solvent Compatibility
- Compatible with most organic and inorganic solvents
- Avoid hydrofluoric acid (HF) and high-concentration fluoride solutions
- Low-concentration fluoride solutions should not remain in contact for extended periods
Do Not Use
- Alkaline cleaning solutions (damages quartz surface)
- Abrasive cleaning materials or brushes
- Detergents (residues can affect measurements)
- Excessive ultrasonic cleaning (>10 minutes)

FAQ
Q: What is the wavelength range of TOQUARTZ® fluorescence quartz cuvettes?
A: TOQUARTZ® fluorescence quartz cuvettes offer exceptional transmission across a wide spectrum from 200nm to 2500nm. Unlike standard glass cuvettes that typically cut off around 350nm, our quartz cuvettes provide excellent transmission in both UV and IR regions with no absorption peaks, making them ideal for a wide range of fluorescence applications.
Q: What is the difference between fluorescence quartz cuvettes and standard quartz cuvettes?
A: Fluorescence quartz cuvettes are specifically optimized for fluorescence measurements with minimal intrinsic background fluorescence, highly polished optical surfaces, and controlled material purity. While standard quartz cuvettes can be used for basic absorbance measurements, fluorescence applications benefit from our specialized manufacturing process that minimizes optical imperfections and background signal.
Q: What is the recommended quartz cuvette cleaning procedure for fluorescence applications?
A: For fluorescence applications where signal purity is critical, we recommend: 1) Immediate rinse with compatible solvent after use, 2) Cleaning with ethanol-water (50:50) mixture, 3) Multiple rinses with distilled water, 4) For persistent organic contaminants, brief treatment with ethanol-HCl (2:1) followed by thorough water rinses, 5) Air drying in a dust-free environment. Avoid detergents, alkaline solutions, and extended ultrasonic cleaning as these can affect background fluorescence.
Q:What path lengths are available for your fluorescence quartz cuvettes?
A: TOQUARTZ® standard fluorescence quartz cuvettes are available with optical path lengths of 1mm, 2mm, 5mm, 10mm (most common), 20mm, 50mm, and 100mm. Custom path lengths between 0.5mm and 100mm can be manufactured to your specifications with a tolerance of ±0.1mm. The appropriate path length depends on your sample concentration and instrument requirements.
Q: What is the absorbance range of your fluorescence quartz cuvettes?
A: TOQUARTZ® fluorescence quartz cuvettes are suitable for measuring sample absorbance from approximately 0.001 A to 3.0 A, depending on your instrument specifications. The high optical quality and minimal stray light characteristics make them ideal for both low and high absorbance applications, with excellent linearity across the measurement range.
