Usage Guide of Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge
Sample Loading Procedure
- Clean and dry the cuvette thoroughly before use.
- Using a micropipette, slowly dispense sample onto the slanted edge.
- Allow liquid to flow down gradually to avoid bubble formation.
- Verify that the sample volume completely fills the measurement zone.
- Place carefully in instrument holder, aligning with light path.
Important Precautions
- Avoid thermal shock – allow cuvette to equilibrate to room temperature before use.
- Do not exceed 100°C thermal limit to prevent damage.
- Never use abrasive materials for cleaning.
- Avoid hydrofluoric acid (HF) which can etch quartz surfaces.
- Inspect for chips or cracks before each use; damaged cuvettes may lead to inaccurate results.
Cleaning and Maintenance
- Daily Cleaning: Rinse with deionized water followed by analytical grade methanol or ethanol.
- For Protein Residues: Use 1% laboratory detergent solution, then rinse thoroughly.
- For Stubborn Contaminants: Soak in 10% nitric acid solution for 30 minutes (avoid HF acid).
- Drying: Use filtered compressed air or nitrogen gas; avoid wiping optical surfaces.
- Storage: Store in original packaging or dust-free container.
- Handling: Always handle by edges, never touch optical surfaces.

FAQ
Q: What are the advantages of four-sided optical transparency in the Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge?
A: The four-sided optical transparency allows multi-angle excitation and emission detection, which is essential for single-cell imaging, confocal microscopy, and time-resolved fluorescence studies requiring full-spectrum access.
Q: Will the open-top design of the Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge cause sample evaporation during long experiments?
A: For short to mid-duration assays, evaporation is minimal due to the small surface area. For longer runs, we recommend using a compatible sealing film or placing the cuvette in a humidity-controlled chamber.
Q: How does the slanted edge of the Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge improve pipetting accuracy?
A: The slanted edge guides the pipette tip naturally into the chamber, reducing the risk of tip misalignment and minimizing bubble formation during sample loading, especially in automated systems.
Q: How does the open-top design of the Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge affect contamination risk?
A: While open-top designs are more exposed, proper lab protocols (e.g., using filtered pipette tips and clean benches) effectively mitigate contamination risks. The benefit is faster access and easier cleaning.
Q: Can the Quartz Micro Fluorescence Cuvette with Open Top and Slanted Edge be used for kinetic assays requiring rapid sample exchange?
A: Yes, the open-top design allows sub-5-second sample replacement, making it ideal for kinetic fluorescence assays and photobleaching studies where timing is critical.
