Designed specifically for fluorometry, this is an excellent choice for nephelometry and spectrophotometry. A negligible variation in absorbance between the 4 optical sides allows readings from any side. The polystyrene cuvettes are accurate in the 340nm to 750nm visible spectral range. The methacrylate cuvettes are accurate throughout the 285nm to 750nm VIS-UV spectral range. Standard 1cm light path. Packaged 100 per covered tray, with 500 per case.
