Description
VAPF100 Long Pathlength Quartz Cuvette with Stopper is a high-sensitivity cuvette featuring a 100 mm optical path length and PTFE stopper sealing.
The extended path length enhances absorbance detection sensitivity, making it ideal for trace and low-concentration measurements in UV/VIS spectrophotometry.
Key Features
- 100 mm long pathlength — improves signal intensity and detection sensitivity for ultra-low concentration samples.
- PTFE stopper design — allows secure sealing, reducing evaporation and contamination during long measurements.
- Fused quartz construction — excellent optical transmission in the UV/VIS range (190–2500 nm) and stable chemical resistance (except HF and certain strong organic solvents).
- Precise dimensional control ensures high measurement repeatability.
- Compatible with most standard UV/VIS spectrophotometers.
Typical Applications
- Trace pollutant and contaminant analysis
- Environmental and water testing
- Low concentration UV/VIS absorption assays
- Biochemical and pharmaceutical analysis
Fused Fabrication Notes
- Can withstand temperatures up to 600 °C.
- Not suitable for hydrofluoric acid (HF).
- Typical dimensional tolerance: ±0.06–0.08 mm.
