(VNE056) 7mL Fluorescence Cuvette with PTFE Lid, Molded, Lightpath 20mm, 5 Clear Walls

Description

VNE056 – 7 mL Quartz Long Path Length Fluorescence Cuvette (20 mm Lightpath, 5 Windows, PTFE Lid, Molded Fabrication)

The VNE056 is a high-precision quartz cuvette designed for fluorescence and absorbance measurements that require enhanced sensitivity without excessive sample volume. With a 20 mm optical path length and 5 optically clear windows, it delivers a balance between signal amplification and efficient sample usage, making it ideal for research, environmental analysis, and quality control applications.

Manufactured from high-purity quartz using molded fabrication, this cuvette provides excellent optical clarity and extremely tight path length tolerances (±0.01 mm). Its broad transmission range from 190–2500 nm supports UV and visible spectroscopy. A PTFE lid provides strong chemical resistance and minimizes sample evaporation during measurement.

Key Features

• 20 mm optical path length: improves signal strength and detection sensitivity compared to standard 10 mm cuvettes.
• 5 optical windows: allows for flexible fluorescence detection from multiple angles.
• Quartz material: excellent UV/VIS transmission (190–2500 nm), resistant to most acids, bases, and organic solvents.
• Molded fabrication: offers the highest precision in optical path length and surface quality.
• PTFE lid: provides excellent chemical resistance and minimizes sample loss through evaporation.
• 7 mL volume: an efficient choice for high-sensitivity analysis with moderate sample consumption.

Typical Applications

• Trace fluorescence and absorbance spectroscopy
• Environmental water analysis
• Pharmaceutical and biochemical testing
• Material science and optical experiments
• UV/VIS spectrophotometry with extended path length

Cuvette Specifications

About Long Path Length Quartz Cuvettes

• Extended path length enhances signal-to-noise ratio and detection sensitivity.
• Excellent chemical compatibility with acids (except HF), bases, and most organic solvents.
• Quartz ensures stable optical performance across UV and visible ranges.
• Ideal for analytical labs, research institutions, and precision spectroscopy.

Note: Handle the cuvette carefully to maintain optical quality. Clean gently after each use to ensure long-term performance.
