Micro Black Wall Cuvette with PTFE Stopper
Low-volume cuvette with black walls for reduced stray light and improved measurement accuracy
Description
Description
These micro cuvettes are designed for UV-Vis spectrophotometry and feature two optical clear walls for accurate absorbance measurements.
The black wall design minimizes stray light and reduces optical interference, improving measurement accuracy, especially for low-signal or high-sensitivity applications.
With reduced sample volume, they are ideal for precious or limited samples.
Equipped with a PTFE stopper, these cuvettes provide effective sealing for volatile or air-sensitive samples.
Available in quartz and optical glass materials, supporting a wide wavelength range from UV to visible applications.
Key Features
- Black walls to minimize stray light and improve signal accuracy
- Two optical clear windows for precise light transmission
- Low sample volume for reduced sample consumption
- PTFE stopper for sealing and reduced evaporation
- Ideal for low-concentration or high-sensitivity measurements
- Compatible with most UV-Vis spectrophotometers
- Available in quartz and optical glass
When should you choose a black wall cuvette?
- When measuring low-concentration samples
- When stray light may affect accuracy
- For high-sensitivity UV-Vis measurements
- When improved signal-to-noise ratio is required
- When working with limited or expensive samples
Fused Cells – for All Type of Solvents
