Usage Guide of Black Fused Quartz Cuvette
Kullanım ve Hazırlık
- Always handle cuvettes using gloves to prevent fingerprints and contamination on optical surfaces.
- Inspect optical windows for cleanliness before use. Hold against light source to check for smudges or particulates.
- Fill cuvettes to appropriate volume (typically 2-3ml for standard 10mm path cuvettes) to ensure proper beam passage through sample.
- For UV applications, use UV-transparent solvents to prepare samples and reference solutions.
- Always cap cuvettes when using volatile solvents to prevent concentration changes during measurement.
Temizlik ve Bakım
- Clean immediately after use - rinse with appropriate solvent first, then with high-purity water.
- For stubborn residues, soak in 5% HCl solution, followed by thorough rinsing with deionized water.
- Dry with clean, compressed air or nitrogen. Never use paper tissues on optical surfaces.
- For optical window cleaning, use spectroscopic-grade solvents like acetone, methanol, or ethanol.
- Store in original container or protective case in a dust-free environment.
Correct Alignment of Black UV Quartz Cuvettes in Spectroscopic Instruments
- Identify the transparent optical windows - these are the two clear sides perpendicular to the black walls.
- Insert cuvette with optical windows facing the light path of the instrument (transparent sides toward light source and detector).
- Black walls should be perpendicular to the incident light to absorb stray radiation.
- Mark one side of the cuvette to maintain consistent orientation between measurements.

SSS
Q: What is a black UV quartz cuvette?
A: A black UV quartz cuvette is a specialized optical cell made from high-purity quartz with black-colored walls and transparent windows. The black walls absorb stray light to minimize interference and background signal, while the transparent windows allow the analytical light beam to pass through the sample for spectroscopic measurements.
Q: Why use a black UV quartz cuvette instead of standard transparent cuvettes?
A: Black UV quartz cuvettes significantly reduce stray light and internal reflections, providing superior performance for applications requiring high sensitivity and accuracy, such as fluorescence spectroscopy and low-concentration DNA/RNA quantification. They deliver improved signal-to-noise ratio and more consistent results for trace analysis applications.
Q: What is the wavelength range for black UV quartz cuvettes?
A: TOQUARTZ® black UV quartz cuvettes transmit light from 120nm in the deep UV through 4500nm in the infrared region. The optical windows have excellent transmission characteristics with no absorption peaks throughout this range, making them suitable for both UV and visible spectroscopy applications.
Q: How do I clean black UV quartz cuvettes?
A: Clean black UV quartz cuvettes by first rinsing with the same solvent used for your samples, followed by spectroscopic-grade acetone or methanol. For thorough cleaning, soak in 5% HCl solution, then rinse extensively with deionized water. Dry with compressed air or nitrogen, never with paper tissues which can scratch the optical surfaces.
Q: What path lengths are available for black UV quartz cuvettes?
A: Standard black UV quartz cuvettes are available in 10mm path length, which is the industry standard. However, we offer custom path lengths ranging from 1mm for high-concentration samples to 100mm for extremely dilute solutions. Common alternatives include 2mm, 5mm, 20mm, and 50mm path lengths.
Q: What is the chemical compatibility of black UV quartz cuvettes?
A: Black UV quartz cuvettes are resistant to most chemicals including acids, bases, organic solvents, and salt solutions. They should not be used with hydrofluoric acid (HF) or hot concentrated phosphoric acid, which can etch quartz surfaces. The high chemical resistance makes them suitable for a wide range of analytical applications.
