SpectraMax M2e Microplate Readers, Molecular Devices (CAT#: STEM-SPO-0023-ZJF)

The SpectraMax M2e Microplate Readers is manufactured by Molecular Devices.
The SpectraMax M2e are multidetection microplate readers with dual-monochromators, dual-mode cuvette ports, and top- and bottom-reading capability. The detection modalities include absorbance and fluorescence intensity. The instrument provides easy conversion and optimization of very low throughput to medium high throughput assays, faster, and more precise results and reagent savings. The combined absorbance and fluorescence intensity assays can be run by issuing a single read command.
