It are designed for precise photometric measurements within the 300 to 900 nm wavelength range. Constructed from high-quality polymethyl methacrylate (PMMA), also known as acrylic, these cuvettes offer excellent optical clarity and chemical resistance, making them suitable for various laboratory applications. With a sample volume capacity ranging from 1.5 to 3.0 mL, these disposable cuvettes ensure consistent and reliable performance. Each cuvette features an arrow mark to indicate the direction of transmission, reducing variation and enhancing measurement accuracy. They are manufactured from pure granular materials under controlled room conditions, ensuring minimal variation in extinction coefficients.
