• Fluorescence is measured at 515 nm following excitation (470 nm) by the Blue LED
• Relative fluorescent output at 515 ± 20 nm (user settable cursor).
• Sample concentration is populated based on a standard curve. There are six choices of units.

A representative spectrum of a 10 nM Fluorescein sample (diluted NIST SRM 1932) measured on a NanoDrop^® ND-3300 Fluorospectrometer is shown above.
