Description

This rectangular cuvette is designed for UV-Vis transmission measurements, featuring two clear optical windows and a graded seal structure for enhanced sample handling.

Compared to standard open cuvettes, this design enables:

• Secure handling of volatile or sensitive samples
• Reduced evaporation during measurement
• Improved repeatability and stability

The long inlet allows easy and controlled sample injection, making it suitable for sealed or semi-closed experimental setups.

Applications

• UV-Vis spectroscopy (transmission measurements)
• Volatile or sensitive liquid analysis
• Chemical and materials research
• Controlled injection or sealed measurement systems

Key Features

• Two clear optical windows for UV-Vis measurements
• Graded seal for improved sealing performance
• Long inlet for controlled sample loading
• Suitable for volatile or reactive samples

Available Materials

• Quartz (190–2500 nm)
• IR Quartz (250–3500 nm)
• Optical Glass (340–2500 nm)

Specifications

Typical configuration includes 10 mm path length and ~3.5 mL volume, suitable for standard UV-Vis measurements.

Comparison with Standard UV-Vis Cuvettes

Standard UV-Vis cuvettes are typically open and designed for routine measurements.

This design provides:

• Better sealing for volatile samples
• Reduced evaporation
• More stable and repeatable results
