TOQUARTZ® Custom Fluorescence Quartz UV Cuvette Development Process
Requirement Analysis
TOQUARTZ® begin by understanding your application needs for Fluorescence Quartz UV Cuvette design, including path length, lid type, and optical window configuration. Our engineers assess technical feasibility and recommend optimal material and geometry.
Technical Drawing & Engineering
Our team creates detailed CAD drawings of the custom Fluorescence Quartz UV Cuvette based on your specifications. We validate dimensions, tolerances, and optical paths to ensure compatibility with your instruments.
Prototype Fabrication
A small batch of Fluorescence Quartz UV Cuvettes is produced for initial testing and evaluation. This allows you to verify fit, transmission, and fluorescence background before mass production.
Quality Verification
Each prototype Fluorescence Quartz UV Cuvette undergoes dimensional inspection and optical testing. We measure transmittance, path length accuracy, and sealing performance to meet your QC standards.
Batch Production & Delivery
Upon approval, we proceed with full-scale production of your custom Fluorescence Quartz UV Cuvette. All units are batch-tested and shipped with documentation, ensuring traceability and consistency.
Usage Guide of Fluorescence Quartz UV Cuvettes
Cleaning Protocol
- Rinse immediately after use with appropriate solvent (usually the solvent used in analysis)
- For routine cleaning, use mild detergent solution followed by thorough rinsing with deionized water
- For persistent residues, soak in 10% nitric acid solution (avoid HF acid)
- Final rinse with spectroscopic-grade acetone or methanol for rapid drying
- Air dry in dust-free environment or use oil-free compressed air
Handling Procedures
- Always handle cuvettes by the non-optical surfaces (top and sides)
- Wear powder-free gloves when handling to prevent fingerprints and contamination
- Place cuvettes in holders gently to avoid chipping or scratching
- Fill to appropriate volume (typically 80% of capacity) to ensure proper measurement
- Ensure optical windows are clean and free from fingerprints before measurement
Storage Recommendations
- Store clean, dry cuvettes in original packaging or dedicated cuvette boxes
- Keep in dust-free environment at room temperature
- Avoid direct contact between optical windows and storage surfaces
- For long-term storage, consider using desiccated containers
- Inspect for dust or damage before use after prolonged storage
Maximizing Measurement Accuracy
- Equilibrate samples to room temperature before measurement
- Eliminate air bubbles by gentle tapping or brief centrifugation
- Maintain consistent orientation in spectrophotometer (align index mark)
- Use matched cuvettes for reference and sample when possible
- For low absorbance measurements, use longer path length cuvettes (10mm+)

FAQ
Q: What is a Fluorescence Quartz UV Cuvette?
A: A Fluorescence Quartz UV Cuvette is a specialized optical cell made from high-purity fused quartz, designed to hold liquid samples for fluorescence spectroscopy and UV-Vis analysis. These cuvettes feature exceptional optical clarity in the UV-Vis-NIR range (200-2500nm) and typically include a lid to prevent contamination and evaporation during analysis.
Q: Why use a Fluorescence Quartz UV Cuvette with Lid?
A: Lids provide several advantages: 1) Prevent sample evaporation during measurements, ensuring concentration stability. 2) Reduce contamination from airborne particles or dust. 3) Minimize spillage risks during handling. 4) Enable secure sample storage for repeated measurements. 5) Necessary for volatile solvents to maintain sample integrity. The PTFE lids on TOQUARTZ® cuvettes offer excellent chemical resistance and sealing properties.
Q: What is the wavelength range for Quartz UV Fluorescence Cuvettes?
A: TOQUARTZ® Fluorescence Quartz UV Cuvettes offer a broad wavelength range of 200-2500nm, covering the UV, visible, and near-infrared regions. This extensive range makes them suitable for diverse spectroscopic applications, from DNA/protein analysis in the UV region to complex fluorescence studies across the visible spectrum.
Q: What path lengths are available for Fluorescence Quartz UV Cuvettes?
A: Standard TOQUARTZ® Fluorescence Quartz UV Cuvettes are available in 1mm, 2mm, 5mm, and 10mm path lengths. Custom path lengths from 0.5mm to 100mm can be manufactured to order. The choice of path length depends on sample concentration and application requirements, with longer path lengths suitable for dilute solutions and shorter path lengths for concentrated samples.
Q: What is the absorbance range of Fluorescence Quartz UV Cuvettes?
A: TOQUARTZ® Fluorescence Quartz UV Cuvettes typically support absorbance measurements in the range of 0-3.0 absorbance units (A.U.), though the practical upper limit depends on the spectrophotometer’s capabilities. For highly accurate work, measurements in the 0.1-1.5 A.U. range are recommended. Custom high-transmission cuvettes are available for applications requiring detection of very low absorbance values.
