4.5 mL Macro Spectrophotometer Cuvettes (VIS & UV-VIS)

Dynalon offers these macro cuvettes in two distinct material formulations to match your specific wavelength requirements. The Visible (VIS) Range variant is molded from optical-grade Polystyrene (PS) designed for applications spanning 340 nm to 750 nm. For broader spectral analysis, the UV-VIS Range variant utilizes a superior grade of Methacrylate, extending transmission performance down into the near-UV range (285 nm to 750 nm)—making it ideal for enzyme rate kinetics, DNA/protein quantification, and scanning assays. Each cuvette features an integrated molded arrow indicating the optimal optical transmission direction to guarantee consistent orientation in the sample chamber.

Key Functional Benefits:

• High-Purity Optical Polymers: Molded from premium Polystyrene (340–750 nm) and UV-transparent Methacrylate (285–750 nm) to minimize light scattering and absorption interference.
• Standardized 10 mm Light Path: Precision-manufactured wall dimensions fit virtually all standard spectrophotometers and fluorometers without requiring chamber adapters.
• Molded Directional Arrow: Features a molded directional indicator on the outer wall to ensure correct alignment relative to the light path, driving run-to-run reproducibility.
• Optimized Macro Volume: Holds up to 4.5 mL maximum liquid volume while operating reliably with minimum fill levels as low as 2.5 mL.
• Dust-Free Storage Trays: Packaged in covered 100-count trays within every 500-count case to protect optical windows from airborne dust, fingerprints, and scratches before use.
