The NanoDrop ND-3300 Fluorospectrometer provides a truly efficient means for microanalysis. Its revolutionary technology allows the measurement of samples as small as 1 µl, and because the user pipettes the sample directly onto the optical source, there is no need for cuvettes or capillaries. The instrument is easy to operate and easy to learn.
The NanoDrop ND-3300 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 virtual filtering for the white LED applications, enables measurements across a wide range of wavelengths using sample volumes of 1-2 µl without cuvettes and costly filter changes.
The excitation source comes from one of the three solid-state LEDs housed in a block adjacent to the measurement pedestal (see below for more details about the LEDs). Emitted light is collected using the traditional 90° angle from the respective excitation source. A 2048-element CCD array detector, covering 400-750 nm, is connected by an optical fiber to the optical measurement surface. The spectrometer is configured with a cut filter to eliminate light transmission below 395 nm.
An added convenience is that no external power supply is required. All of the operating power is supplied by the USB port on the PC.
The ND-3300 offers many benefits:
Full-spectrum analyses of fluorescence emission (400-750 nm)
For measuring fluorophores and reagents such as PicoGreen, RiboGreen, Hoechst, FITC, Cy3-Alexa555, Cy5-Alexa647 and quantum dots
1-2 µl of sample
Higher sensitivity: can detect pg/ul range of dsDNA
