BRAND's plastic cuvettes are manufactured from the highest quality virgin resins for highest optical quality and are an excellent choice for most spectrophotometry applications in the visible range. Manufactured from polymethyl methacrylate (PMMA), they provide accurate, reliable results. Choose PMMA for determinations above 300nm. When performing assays above 340nm and where cost is a concern, choose PS. (For wavelengths below 300nm, see our UV-cuvettes). These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes and are compatible with most spectrophotometers and photometers. All BRAND cuvettes are manufactured from scratch-resistant materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.
Easy to Use: BRAND plastic disposable cuvettes include an arrow mark to indicate direction of transmission and reduce variation.
Options for Most Needs: Available in both macro and semi-micro sizes to adapt to the needs of most laboratory applications. Semi-micro cuvettes require only 1.5mL of sample volume to provide reliable, accurate results.
Performs Consistently: Cuvettes are manufactured from high-quality materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.
The PMMA cuvettes should not be used at temperatures above 95°C
