Sarstedt disposable square cuvettes are available in polystyrene and acrylic.
Due to the optical characteristics of the material, polystyrene cuvettes are suitable for use down to 330 nm, with a spectral transmission of 70 – 80% at a wavelength of 334 nm.
Acrylic cuvettes, due to their excellent optical clarity, are particularly suitable for measurements in the ultraviolet range. They can be used down to approximately 300 nm. Transmission, for example, at 334 nm is approximately 80-90 %.
Square cuvettes are available as 10x10mm cuvettes and as 10 x 4mm semi-micro cuvettes with a 10 mm optical pathway. A further option with 4 optically clear sides is also available for fluorescence measurements.
Push caps are available for cuvettes with round apertures and a 10 mm optical pathway
