(VNE052) 1.75mL Fluorescence Cuvette with PTFE Lid, Molded, Lightpath 5mm, 5 Clear Walls

Description

VNE052 – 1.75 mL Quartz Fluorescence Cuvette (5 mm Lightpath, 5 Windows, PTFE Lid, Molded Fabrication)

The VNE052 is a high-precision quartz cuvette designed for fluorescence and absorbance applications where small sample volume and high measurement accuracy are essential. With a 5 mm optical path length and 5 optically clear windows, this cuvette is ideal for front-face fluorescence, right-angle detection, and high-concentration sample analysis where a standard 10 mm path length may lead to oversaturation.

Manufactured using molded fabrication, this cuvette delivers superior dimensional accuracy (±0.01 mm), excellent optical clarity, and enhanced chemical durability. Molded quartz cuvettes are one-piece structures without bonded seams, providing maximum resistance to strong acids, bases, and aggressive organic solvents. The PTFE lid offers reliable sealing and chemical resistance, reducing sample evaporation during extended measurements.

Chemical Compatibility

Molded quartz cuvettes are resistant to a broad range of corrosive and organic chemicals, making them suitable for demanding analytical environments.

• ✔ Compatible with strong acids and bases (except HF), aqueous buffers, alcohols, and most organic solvents.
• ✔ Excellent performance with aggressive solvents such as toluene, acetone, chloroform, and carbon tetrachloride.
• ❌ Not compatible with hydrofluoric acid (HF).
• Durable for long-term use in harsh chemical environments with minimal risk of damage.

Key Features

• 5 mm optical path length: prevents oversaturation for concentrated samples and enables accurate fluorescence or absorbance measurements.
• 5 optical windows: allows multiple detection configurations, including right-angle and front-face fluorescence.
• Molded fabrication: one-piece design ensures high precision and superior chemical resistance.
• PTFE lid: provides strong resistance to solvents and minimizes sample loss through evaporation.
• 1.75 mL sample volume: ideal for applications with limited or valuable samples.

Typical Applications

• Fluorescence and absorbance spectroscopy
• High-concentration or high-absorbance sample analysis
• Pharmaceutical, biochemical, and environmental testing
• Research and QA/QC laboratories

Cuvette Specifications

Notes on Use

• Molded cuvettes offer the highest optical precision and chemical resistance among all quartz fabrication types.
• Suitable for long-term use with harsh organic solvents without staining or seam degradation.
• Clean immediately after use to maintain maximum optical performance.
