High Quality 104-10-40 Cuvette 104-QS SEMI-MICRO CELLS In Stock-Labcan Scientific

Product Description

Part No.: 104-10-40

Series: 104-QS Semi-Micro Absorption Cuvette

Hellma 104-10-40 is German-manufactured semi-micro absorption cell fabricated from Suprasil® QS high-purity fused quartz glass, supplied with original PTFE sealing lid. Optimized for UV-Vis-NIR absorbance measurement with reduced sample consumption compared to standard macro cuvettes.

Precision-polished dual optical windows provide excellent parallelism, low stray light and highly reproducible photometric results. Adopts glue-free thermal fusion bonding construction for outstanding chemical resistance and zero risk of adhesive leaching. Standard outer dimension fits Shimadzu, Hitachi, Thermo, Agilent, PerkinElmer and most mainstream laboratory spectrophotometers. The matching PTFE lid prevents sample evaporation and oxidation, suitable for kinetic measurement and routine quantitative analysis.

Hellma® high precision quartz glass micro cell for absorption measurements in the UV/Vis range, 10 mm pathlength, with lid
Dimension 45 x 12.5 x 12.5mm, Wavelength 200-2500nm, Base Thickness 3.2 mm, Number of Windows 2
RoHS Conformity ja, REACH Conformity ja
Hellma® precision cuvettes are manufactured in Germany and are suitable for all common spectrophotometers.
Highest precision
Hellma® precision cuvettes are characterized by maximum precision in terms of pathlength accuracy and parallelism. This guarantees continuously reproducible measurement results.
Chemically resistant and thermally bonded
Hellma® precision cells are thermally bonded and not glued, making them highly resistant to temperatures and chemicals. This prevents unintentional leakage of liquids.
Excellent transmission
The use of a selected special optical glass gives Hellma® precision cuvettes excellent transmission > 80 % for exact measurement results.
Safe handling
Hellma® precision cuvettes have chamfered edges that enable safe and comfortable handling. The risk of chipping is also minimized.
Sustainable
Hellma® precision cuvettes can be easily cleaned and reused and therefore remain in use for a long time. A sustainable and environmentally friendly alternative!
Certified production
Hellma® precision cuvettes are manufactured in accordance with EN ISO 9001 / EN ISO 14001 and meet the highest optical standards. The declaration of conformity is available for download on the Hellma website. Further certificates (certificate of compliance 2.2 and inspection certificate 3.1) are available on request.

· Outstanding surface flatness of optical windows: 0.001 mm (1 µm)

· Excellent temperature stability and chemical resistance, achieved by thermally bonded individual components (effectively monolithic structure)

· Minimum guaranteed transmittance of 82% from 200 nm to 3500 nm (subject to material specifications)

Cuvettes are not all the same, even if they sometimes appear identical. The difference lies in the details and can be crucial for measurement results. Take our cuvette windows, for example, which boast outstanding quality and a flatness tolerance of more than 0.001 mm (1 μm). The parallelism of both window surfaces relative to one another is just as important. Our high-precision production guarantees that the frontal deformation of the wave of a cuvette window is less than 4 lambda, which works out at approximately 0.001 mm (1 μm) if lambda = 546 nm. The high level of flatness demonstrates that the cuvettes from Hellma Analytics are setting standards. Overall, an ideal foundation for conducting reliable, reproducible and exact measurements.
