- Use appropriate fittings when connecting to flow systems to prevent leakage and avoid over-tightening.
- Ensure that the flow path is properly aligned with the light source and detector in your instrument.
- Verify compatibility with your solvents and samples before extended use.
Cleaning and Maintenance
- Flush with appropriate solvent after each use to prevent sample residue accumulation.
- For stubborn residues, use dilute acid solutions followed by thorough rinsing with deionized water.
- Avoid abrasive cleaning materials that could scratch optical surfaces.
- Dry with filtered, oil-free compressed air or nitrogen before storage.
- Store in a clean, dust-free container when not in use.
Temperature Considerations
- While the cuvette can withstand temperatures up to 1100°C, avoid rapid temperature changes to prevent thermal shock.
- For high-temperature applications, allow for gradual heating and cooling (recommended rate < 5°C/min).
- Verify that any connected tubing and fittings are compatible with your operating temperature.
Flow Rate Recommendations
- For standard 10 mm path length cuvettes, optimal flow rates range from 0.5 to 5 mL/min for analytical applications.
- Higher flow rates may be used but ensure sufficient residence time for accurate measurements.
- For viscous samples, adjust flow rates accordingly to prevent pressure buildup.
