Fluorescence Cuvette with PTFE Stopper
Sealed cuvette for accurate fluorescence measurements with four optical windows
Description
Description
These fluorescence cuvettes are designed for fluorometry applications and feature four optical clear walls for multi-directional light transmission.
Fluorescence measurements require detection at a 90° angle to the excitation light, making four optical windows essential for accurate results.
Equipped with a PTFE stopper, these cuvettes provide effective sealing, making them ideal for volatile, sensitive, or air-reactive samples.
Available in quartz and optical glass materials, suitable for UV and visible wavelength applications.
Key Features
- Four optical clear walls for fluorescence detection
- Designed for 90° emission measurement geometry
- PTFE stopper for improved sealing performance
- Suitable for volatile and air-sensitive samples
- High optical clarity for accurate fluorescence results
- Compatible with most fluorometers
- Available in quartz and optical glass
When should you choose a fluorescence cuvette with stopper?
- For fluorescence spectroscopy measurements
- When emission is detected at 90° to excitation light
- When working with volatile or sensitive samples
- When sealing is required to prevent evaporation or contamination
