Polymethylmethacrylate (PMMA) Cuvette 2.5-4.5 mL, 500/PK, Brandtech Scientific, Inc

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 polystyrene (PS) or polymethyl methacrylate (PMMA), they provide accurate, reliable results.

Choose PS for determinations above 340nm, and where cost is a concern. When performing assays above 300nm, choose PMMA. (For wavelengths below 300nm, see BrandTech's UV-cuvettes). Features:

• Macro and semi-micro sizes so most sample volumes are compatible with spectrophotometers and photometers
• Scratch-resistant
• Grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient
