Hellma® high precision quartz glass macro cells for absorption measurements in the UV/Vis/NIR range, 1 to 50 mm path length, with stopper.

• Cells made of extended range quartz glass or high-performance quartz glass

• Wavelength range from 200 to 3500 nm
• Path length: 1 to 50 mm
• With PTFE stopper
• Volume: 350 to 17500 μl

Hellma® precision cells are 100% manufactured in Germany and are suitable for all common spectrophotometers.

Highest precision: Hellma® precision cells are characterized by the highest precision in path length accuracy and parallelism. This guarantees continuously reproducible measurement results.
  
Chemically resistant and thermally bonded: Hellma® precision cells are thermally bonded and not glued, which gives them a very high resistance to temperatures and chemicals. This prevents unintentional leakage of liquids.

Excellent transmission: By using selected high-performance quartz glasses, Hellma® precision cells achieve excellent transmission >82% for exact measurement results.

Secure handling: Hellma® precision cells have chamfered edges that enable safe and comfortable handling. In addition, the risk of splintering is minimised.

Sustainable: Hellma® precision cells can be easily cleaned and reused and thus remain in use for a long time. A sustainable and environmentally friendly alternative.

Hellma® precision cells are manufactured according to EN ISO 9001/EN ISO 14001 and meet the highest optical standards. The declaration of compliance is available for download on the Hellma website. Further certificates (factory certificate 2.2 and acceptance test certificate 3.1) are available on request.

Cell pairs are spectrally calibrated.
