BRAND plastic cuvettes are an excellent choice for most spectrophotometry applications in the visible range. Manufactured from polystyrene (PS), they provide accurate, reliable results, even at wavelengths as low as 300nm. BRAND plastic cuvettes are compatible with most spectrophotometers and photometers.
BRAND plastic disposable cuvettes include an arrow mark to indicate direction of transmission and reduce variation.
Cuvettes are manufactured from high-quality materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.
