Usage and Care Guidelines
Proper Handling
- Always handle cuvettes by the non-optical sides (typically the frosted or ribbed surfaces)
- Avoid touching optical windows with bare fingers to prevent oil deposits
- Use lint-free gloves when handling for sensitive measurements
- When placing in instruments, ensure correct orientation with path length aligned with light beam
- Avoid rapid temperature changes that could cause thermal shock
Cleaning Procedure
- Rinse immediately after use with appropriate solvent (often distilled water or acetone)
- For stubborn residues, soak in 1:1 methanol/HCl solution (avoid HF which damages quartz)
- Use laboratory detergent solutions for biological samples
- Rinse thoroughly with distilled water after cleaning
- Allow to air dry in dust-free environment or use filtered compressed air
- For critical applications, verify cleanliness with blank measurements
Storage Recommendations
- Store in original protective packaging or dedicated cuvette holders
- Keep in dust-free, dry environment
- Cover open tops with laboratory film or dedicated covers when not in use
- Avoid contact with hard surfaces that could scratch optical windows
- Label dedicated cuvettes for specific applications to prevent cross-contamination
Usage Precautions
- Avoid using with hydrofluoric acid (HF) which etches quartz
- Prevent mechanical shocks that could cause micro-fractures
- When using in high-temperature applications, allow gradual heating/cooling
- Fill to appropriate levels (typically 2/3 capacity) to avoid spillage
- For kinetics studies, ensure magnetic stirring bars do not contact walls
- Check compatibility with your instrument specifications before use

FAQ
Q: How does the open-top design affect sample evaporation during fluorescence analysis?
A: The Quartz Fluorescence Cuvette without Cap does not prevent evaporation, especially during long-duration assays or under heating. For short-term fluorescence measurements, evaporation is minimal and manageable. If needed, temporary sealing with lab film or custom lids is possible. Always monitor sample volume in high-temperature or long-read protocols.
Q: Will the lack of a cap increase the risk of contamination during fluorescence assays?
A: The open design of the Quartz Fluorescence Cuvette without Cap does expose the sample to ambient air. However, in controlled lab environments, contamination risk is minimal. For sensitive assays, users can cover the top with sterile film or use laminar flow hoods. Proper handling protocols are recommended.
Q: How does the open-top design affect light path consistency in fluorescence measurements?
A: The Quartz Fluorescence Cuvette without Cap maintains a fixed optical path length through its precision-machined geometry. The absence of a cap does not affect light alignment. Optical surfaces are polished to ensure minimal scattering. Consistent path length is maintained across batches.
Q: Can the Quartz Fluorescence Cuvette without Cap be used for time-sensitive fluorescence assays?
A: Yes, the open-top design of the Quartz Fluorescence Cuvette without Cap allows rapid reagent addition without removing any closure. This is especially useful in time-sensitive assays such as DNA intercalation or enzyme kinetics. It minimizes delay between reagent mixing and fluorescence reading. This improves reproducibility across multiple samples.
Q: Will the open-top Quartz Fluorescence Cuvette affect background fluorescence levels?
A: No, the Quartz Fluorescence Cuvette without Cap is made from ultra-pure quartz with minimal autofluorescence. The absence of a cap does not introduce background signal. Optical surfaces are polished to reduce stray light. It is suitable for low-signal fluorescence detection.
