📘 Material Specifications
All Scuvette quartz cuvettes are manufactured from high-purity synthetic quartz glass (JGS1 / QSI grade) with the following optical properties:
| Property | Value |
|---|
| Transmission range | 190 – 2500 nm |
| Refractive index (at 587.6 nm) | 1.4585 |
| Strain level | Class 1 (≤ 4 nm/cm) |
| Bubbles / inclusions | None (Class 0) |
| Thermal expansion | 5.5 × 10⁻⁷ / °C |
🔬 Common Applications
- UV-Vis Spectrophotometry — Standard 10mm path cuvettes for absorbance measurements in pharmaceutical and chemical analysis.
- Fluorescence Spectroscopy — 4-way clear cuvettes for excitation and emission detection from any angle.
- Micro-volume Analysis — Micro and sub-micro cuvettes (18–350 µL) for DNA, protein and enzyme kinetics.
- Flow Injection Analysis (FIA) — Flow-through cells for continuous monitoring and HPLC detection.
- High-Temperature Chemistry — Alumina plates, quartz boats and crucibles for TGA, DSC and combustion analysis up to 1700°C.
📐 Path Length Selection Guide
| Path Length | Typical Use Case | Sample Volume |
|---|
| 1 mm | High-concentration samples | ~350 µL |
| 2 mm | Moderate concentration | ~700 µL |
| 5 mm | General purpose | ~1.5 mL |
| 10 mm | Standard UV-Vis | ~3.5 mL |
🧼 Cleaning & Maintenance
Quartz cuvettes require careful handling to maintain optical clarity:
- Rinse with distilled water immediately after use.
- For organic residues, soak in ethanol or acetone for 10 minutes, then rinse.
- Avoid abrasive materials — use soft lint-free wipes only.
- Do not use strong alkaline solutions (pH > 12) which etch quartz surfaces.
- Store in a clean, dry container away from dust.
