Molecular Devices Spectramax Gemini EM Fluorescence Microplate Reader

The Molecular Devices Gemini EM is built on the Gemini platform delivering high quality top and bottom reading for both solution and cell based assays. The Gemini EM can sample a variety of formats, from 6- to 384-well microplates, in different modes, such as endpoint, spectral scan, kinetic, and well scan. This reader's dual monochromators for excitation and emission cover the wavelength selection from 250 to 850 nm. Utilize both top and bottom fluorescence reading for the best optical sensitivity, and read up to four wavelength pairs in endpoint and kinetic measurements.

The Gemini EM offers superb accuracy and reproducibility of results, possible with AutoPMT electronics, calibration for comparing RFUs between samples, consistent temperature regulation, programmable Automix, gentle movement, seamless automation, and comprehensive reader validation.

Applications for the Gemini EM include enzyme assays, protein quantitation, microbial growth, ELISAs and immunoassays, transporter assays, nucleic acid quantitation, phosphotases/kinases, reporter gene assays, and cell viability, proliferation, and cytotoxicity.

The Molecular Devices Spectramax Gemini EM Microplate Reader includes:
  • > Windows 7 Data Station with Pre-Loaded Softmax Pro Software 6.3.1
  • > Operator's Manual
  • > Interface Cable
  • > Molecular Devices Fluorescence Validation Report
  • > Full 90 Day Part and Labor Warranty
