BRAND Polystyrene Cuvettes, Macro, 2.5–4.5mL, Pkg. of 100

Made from highest-quality virgin resins, these Cuvettes have the highest optical quality. Use them for work in the visible and near-UV range. Compatible with most spectrophotometers and photometers using a standard 10mm path length.
Because Polystyrene Cuvettes are sorted robotically, each package contains only those from the same mold cavity. The result is the lowest possible variance in extinction coefficient and optimized measurement accuracy. Macro size provides reliable, accurate results with a minimum fill volume of 2.5mL and 4.5mL maximum. An arrow mark indicating direction of transmission simplifies processes and reduces variation. Packaged in dust-free, low-scratching expanded polystyrene to ensure they arrive in pristine condition, contaminant-free and with optical quality windows. 2.5–4.5mL. Pkg. of 100.
