Usage Guide of Quartz Micro Cuvette
Sample Handling
- Fill cuvettes using precision pipettes to avoid air bubbles. For micro-volume models, ensure the minimum recommended volume is maintained for accurate readings.
Instrument Placement
- Insert cuvettes with the optical windows facing the light path. Most TOQUARTZ cuvettes have two clear sides and two frosted sides; position the clear sides perpendicular to the light beam.
Temperature Considerations
- While quartz can withstand high temperatures (up to 1100°C), avoid rapid temperature changes exceeding 100°C/minute to prevent thermal shock.
Cleaning Protocol
- After each use, rinse with appropriate solvent, followed by distilled water. For stubborn residues, soak in 50% nitric acid solution for 30 minutes, then rinse thoroughly with distilled water.
Storage Recommendations
- Store clean, dry cuvettes in the original protective case or dedicated dust-free container to protect optical surfaces. Avoid direct contact between optical windows.
Handling Precautions
- Always hold cuvettes by the frosted sides or tops to prevent fingerprints on optical windows. Use lint-free gloves or tissues when handling.
