How to Choose the Right Cuvette for Your Application
🧠 1. Select by Measurement Type
| Application | Recommended Cuvette |
|---|---|
| UV-Vis Absorbance | 2 Optical Windows (Standard Cuvette) |
| Fluorescence | 4 Optical Windows |
| Low signal / stray light sensitive | Black Wall Cuvette |
| Routine / high-throughput | Disposable Cuvette |
🌈 2. Select by Material (Critical for Wavelength Range)
| Material | Wavelength Range | Application |
|---|---|---|
| Quartz | 190 – 2500 nm | UV + Visible (recommended) |
| Optical Glass | 340 – 2500 nm | Visible only |

📏 4. Select by Path Length
| Path Length | Application |
|---|---|
| 10 mm | Standard measurements |
| 1–5 mm | High concentration samples |
| >10 mm | Low concentration detection |
🔒 5. Choose the Right Closure Type
| Type | Best For | Sealing Level |
|---|---|---|
| Lid | Routine testing | Low |
| Stopper | Volatile or sensitive samples | Medium |
| Screw Cap | Storage / long-term testing | High |
