FAQ
Q1: How should I properly clean quartz cuvette?
A: Recommended protocol:
1. Rinse with appropriate solvent (acetone for organics)
2. Soak in 10% HNO₃ (30 mins for inorganic residues)
3. Never use abrasive cleaners
4. Ultrasonic cleaning acceptable at 40kHz max
Q2: What's the temperature limit for measurements?
A: Continuous use:
- Standard models: -80°C to +250°C
- High-temp versions: Up to +1000°C (with special holders)
Q3: How do I verify quartz cuvette quality?
A: Performance checks:
1. Empty absorbance scan (should be <0.05AU at 220nm)
2. Ethanol index matching test
3. Polarization sensitivity check
