Hellma® macro cell for absorption measurements in the visible range, 20 mm pathlength, with lid. Hellma® macro cells are manufactured 100% in Germany and are suitable for all common spectrophotometers. Highest precision Hellma® precision macro cells are characterized by maximum precision in terms of pathlength accuracy and parallelism. This guarantees continuously reproducible measurement results. Chemically resistant and thermally bonded Hellma® macro 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® macro cells excellent transmission > 80 % for exact measurement results. Safe Handling Hellma®macro cells have chamfered edges that enable safe and comfortable handling. The risk of chipping is also minimized. Sustainable Hellma® macro cells can be easily cleaned and reused and therefore remain in use for a long time. A sustainable and environmentally friendly alternative! Certified production Hellma® macro cells 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.
