Description
VAOB85 Bonded Quartz Fluorescence Cuvette is a 4-window cuvette with a 28 mm optical path length and an 8.5 ml volume.
It features a wide clear wall design, ideal for fluorescence measurements that require side detection and enhanced optical clarity.
Bonded fabrication ensures cost-effective construction and good chemical resistance under typical laboratory conditions.
Key Features
- 28 mm optical path length — suitable for high-sensitivity fluorescence and absorbance measurements.
- 4-window design — allows side detection, enabling fluorescence excitation and emission experiments.
- Bonded fabrication — provides stable performance for most general laboratory applications.
- Wide wall geometry — optimized for fluorescence setups with precise optical alignment.
- Broad wavelength range — 190 – 2500 nm, suitable for UV/VIS and NIR applications.
Typical Applications
- Fluorescence spectroscopy (side detection and excitation).
- UV/VIS absorbance and transmission studies.
- Routine lab assays and standard optical experiments.
- Educational and R&D environments where cost-effective bonded construction is preferred.
Bonded Fabrication Notes
- Bonded fabrication offers cost-effective performance for routine measurements.
- Not recommended for high-temperature applications or long-term solvent exposure.
- Bonded seams are more sensitive to aggressive organic solvents compared to fused fabrication.
- Suitable for aqueous and mild solvent environments.
