Gemini Microplate Fluorometer

Gemini microplate fluorometerGemini EM is a microplate spectrofluorometer from Molecular Devices. It has dual scanning monochromators that allow for 1 nm increment selection over the wavelength range of 250 - 850 nm. Bandwidth for both excitation and emission is 9 nm. Lamp source is a Xenon flash lamp (1 Joule/flash). Scanning options are endpoint, kinetic, spectral scanning, and well scanning. Microplate formats include 6-384 well plates. Top and bottom readings are available. Additional features include shaker and temperature control.
