Usage Guide of Sub-micro Fused Quartz Cuvettee
How to Clean Sub-micro Quartz Cuvettes
- 1. Rinse immediately after use with appropriate solvent (typically deionized water or analytical grade ethanol)
- 2. For stubborn residues, soak in 0.1M HCl solution (avoid HF which will damage quartz)
- 3. For organic contaminants, use mild detergent solution followed by thorough solvent rinse
- 4. Rinse 5-10 times with deionized water
- 5. Allow to air dry in dust-free environment or use filtered compressed air
- 6. For critical applications, verify cleanliness with baseline measurement
Solvent Compatibility
- Water-based buffers and solutions
- Alcohols (ethanol, methanol, isopropanol)
- Most organic solvents (acetone, acetonitrile, DMSO)
- Dilute acids and bases (except HF)
- Saline solutions
Special Considerations for Air Free Cuvettes
Always handle cuvettes by the non-optical sides to avoid fingerprints and contamination
Use lint-free gloves or finger cots when direct handling is necessary
Store in original packaging or dedicated cuvette holders
Keep in dust-free, dry environment when not in use
Avoid rapid temperature changes which may cause thermal stress
Inspect optical surfaces before use under good illumination
Establish regular cleaning protocols in your laboratory procedures
Path Length Verification
Use interference method with monochromatic light source
Verify with standard reference materials (e.g., potassium dichromate solutions)
Use calibrated micrometer for physical measurement when possible
Document verification in laboratory records for traceability
Extending Cuvette Lifespan
Clean immediately after use before samples can dry or adhere
Avoid scratching optical surfaces during cleaning
Dedicate specific cuvettes to specific applications when possible
Store with compatible stoppers or caps to prevent dust accumulation
Implement regular inspection protocol for optical clarity

FAQ
Q: How do I clean sub-micro quartz cuvettes without damaging them?
A: Clean immediately after use with appropriate solvent rinses (water, ethanol, or acetone). For protein residues, use mild detergent solution. Never use hydrofluoric acid or abrasive materials. Rinse thoroughly with deionized water and air dry in a dust-free environment. Avoid touching optical surfaces.
Q: What is the wavelength range for sub-micro quartz cuvettes?
A: TOQUARTZ® sub-micro quartz cuvettes transmit light from 200nm to 2500nm, covering UV, visible, and near-infrared regions. This makes them suitable for a wide range of spectroscopic applications including UV absorbance, visible spectroscopy, and NIR analysis, unlike glass cuvettes which absorb UV light.
Q: What solvents are compatible with sub-micro quartz cuvettes?
A: TOQUARTZ® Sub-micro quartz cuvettes are compatible with most laboratory solvents including water, alcohols, acetone, DMSO, most acids and bases. They are NOT compatible with hydrofluoric acid (HF) and hot concentrated phosphoric acid, which can etch or damage quartz surfaces.
Q: How accurate is the path length in sub-micro quartz cuvettes?
A: TOQUARTZ® sub-micro quartz cuvettes feature path length accuracy of ±0.1mm standard, with ±0.05mm available for select models. This precision ensures reliable quantitative analysis, especially important for applications like DNA/RNA concentration determination where Beer-Lambert calculations rely on accurate path length.
Q: Are sub-micro quartz cuvettes reusable?
A: Yes, sub-micro quartz cuvettes are fully reusable with proper cleaning and maintenance. Their chemical resistance and durability make them suitable for repeated use, providing significant cost advantages over disposable options, particularly for routine analytical procedures.
