UV-Vis Quartz Cuvette with Graded Seal (Rectangular, 2 Optical Windows)
Designed for UV-Vis transmission measurements with sealed sample handling, featuring a long inlet for controlled sample loading and improved measurement stability.
Description
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.
