Disposable Cuvettes

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.

Since the seventies, Sarstedt has been renowned as a supplier of high-quality plastic disposable cuvettes made from polystyrene (PS) and acrylic (PMMA). With a view to serving the UV range down to 220 nm which is gaining more and more importance, our product range has been complemented by a new UV transparent disposable cuvette
Due to its optical characteristics, polystyrene is ideal for use in the visual range and the UV transparent range down to 330 nm. At 334 nm, for instance, polystyrene has a spectral transmission ratio of about 70 to 80 %.

Acrylic cuvettes, on the other hand, stand out for their enhanced light transmission in the UV range and can be
used down to approximately 300 nm. Their spectral transmission ratio at 334 nm, for instance, is between 80 to 90%.
