Cuvette holder for use with FL-QM-UNI-HLDR sample tray
The cuvette holder in the Fluorolog-QM spectrofluorometer is an essential component that securely holds the sample cuvette during fluorescence measurements. Proper maintenance and timely replacement are crucial to ensuring accurate, repeatable, and contamination-free results. Regular maintenance helps prevent sample contamination, optical misalignment, and measurement errors.
Maintenance and replacement:
- Wipe the cuvette holder with a lint-free cloth to remove dust and fingerprints.
- Use compressed air to blow out any dust or debris from the holder’s interior.
- Regularly inspect for: Scratches or residue buildup inside the holder that may affect optical paths. Loose or misaligned clamps that may cause cuvette instability. Corrosion or wear if working with aggressive chemicals.
Despite regular maintenance, the cuvette holder may need replacement due to wear, damage, or performance degradation.
When to replace the cuvette holder:
- Physical damage: Cracks, warping, or corrosion that affects cuvette positioning.
- Persistent contamination: If deep cleaning does not remove residues affecting optical paths.
- Misalignment issues: If repeated adjustments fail to keep the cuvette in the correct optical position.
- Temperature control failure: If the thermostated holder no longer maintains stable temperature control.
