The NanoDrop^® ND-3300 Fluorospectrometer is a multi-source optical instrument for measuring fluorescence. This space-saving fluorometer offers exclusive features that allow investigators the flexibility to use fluorometry in valuable new ways.

The uniquely clean optics of the patented retention system, combined with proprietary signal processing for the white LED applications, enables measurements across a wide range of wavelengths using sample volumes of 1-2 ul without cuvettes and costly filter changes.

The excitation source comes from one of three solid-state LED's, which are oriented 90° to the detector. The excitation maxima of each LED is:

• UV : 365 nm - filtered (<5% transmittance above 400nm)
• Blue : 470 nm
• White : 500 - 650 nm
