- Avoid Abrasives – Never scrub with brushes that can scratch surfaces.
Storage & Handling
- Store in original cases or soft holders.
- Handle by the edges to avoid fingerprint smudges.
- Label cuvettes if reused for specific chemicals.
When to Replace Cuvettes
- Visible scratches or cracks.
- Inconsistent absorbance readings.
- Cloudiness or permanent staining.
Conclusion
Proper cuvette maintenance ensures consistent results and cost savings. Follow cleaning and storage protocols to maximize their lifespan.
