flow-through cells, 137

cuvette type 137-QS made of high-performance quartz glass, wavelength range from 200 nm to 2500 nm, pathlength 2 mm, aperture (HxW)20 x 9 mm, with in/outlet tubes, volume 520 µl.
Hellma® precision cuvettes are manufactured 100% 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.
