Kullanım ve Bakım Yönergeleri
Taşıma ve Ölçüm
- Handle cuvettes by the frosted or non-optical surfaces only to prevent fingerprints on optical windows.
- Ensure correct orientation in the instrument with the triangular face perpendicular to the excitation beam.
- Fill to the recommended volume (typically 2-3ml) to ensure proper beam positioning through the sample.
- Allow temperature equilibration for heat-sensitive applications to prevent thermal gradients.
Temizlik Prosedürü
- Rinse immediately after use with appropriate solvent (often deionized water or ethanol).
- For persistent residues, soak in 10% HNO₃ solution (avoid HF which damages quartz).
- Rinse thoroughly with ultrapure water after cleaning with any chemical solution.
- Dry with filtered air or nitrogen; avoid paper towels that can scratch optical surfaces.
Depolama Önerileri
- Store clean, dry cuvettes in original protective cases or dedicated dust-free containers.
- Maintain storage environment at constant temperature and humidity to prevent condensation.
- Avoid storage near corrosive chemicals or volatile substances that could deposit on optical surfaces.
- Consider desiccated storage for long-term preservation of optical quality.
Bakım İpuçları
- Periodically inspect for scratches, chips, or chemical etching under proper lighting.
- Verify optical performance with standard reference materials if measurement drift is observed.
- Replace cuvettes if any optical surface damage is detected to prevent measurement errors.
- Keep record of cuvette usage and cleaning cycles for quality assurance purposes.

SSS
Q: How does the triangular shape benefit fluorescence detection compared to rectangular cuvettes?
A: The triangular geometry minimizes stray light and reduces excitation beam reflection into the detector. This improves signal-to-noise ratio, especially in low-concentration fluorescence assays. It also enables precise 90° excitation-emission configurations. This is critical for accurate quantum yield and anisotropy measurements.
Q: How does the Triangular Quartz Fluorescence Cuvette perform in high-sensitivity fluorescence assays?
A: Its geometry reduces internal scattering and enhances emission collection efficiency. This makes it ideal for detecting low-abundance analytes such as proteins or metabolites. The four-sided transparency allows flexible detector positioning. Combined with high-purity quartz, it ensures minimal background fluorescence.
Q: Are there any limitations when using the Triangular Quartz Fluorescence Cuvette in automated fluorescence systems?
A: The unique shape may require custom holders or adapters in some automated readers. However, we offer dimension-matched designs for most commercial systems. The screw cap and flow ports are compatible with robotic pipetting and fluid handling. Contact us for integration support.
Q: Can the Triangular Quartz Fluorescence Cuvette be used in oxygen-sensitive fluorescence assays?
A: Yes, the screw cap and optional sealing features allow inert gas purging. This is essential for assays involving oxygen-sensitive fluorophores or enzymatic reactions. The sealed design maintains an anaerobic environment during measurement. It ensures reproducibility in redox-sensitive fluorescence studies.
Q: Can the Triangular Quartz Fluorescence Cuvette be used in flow-through fluorescence systems?
A: Yes, the cuvette can be customized with inlet and outlet ports for continuous flow applications. This is ideal for kinetic fluorescence assays or real-time monitoring of reactions. The triangular geometry ensures minimal dead volume and consistent flow path. It supports integration with peristaltic or syringe pumps.
