Microplate Reader

Microplate readers, also known as microplate photometers, are instruments which are used to detect biological, chemical, or physical events of samples in microtiter plates. Marshall Scientific has a wide assortment of microplate readers, however our most popular are the Molecular Devices Spectramax Microplate Readers. The Molecular Devices Microplate Readers that we carry include: Versamax, Gemini, Gemini EM Fluorescence, Gemini XS, 190, 250, 340, and the 384 Plus. Most of our Molecular Devices Microplate Readers come with a computer with the preinstalled software necessary to run the machines (check product description to verify if preloaded computer is included). Please take a look at our inventory that is currently in stock and feel free to give us a call or send us an email if you have any questions.

Molecular Devices SpectraMax M2e Multilabel Microplate Reader Molecular Devices SpectraMax M2e Multilabel Microplate Reader

Molecular Devices SpectraMax M2e Multilabel Microplate Reader


SpectraMax M2e is a dual-monochromator, multi-detection microplate reader with a dual-mode cuvette port and 6-384 microplate reading capability. Detection modalities include absorbance (UV-Vis Abs) and fluorescence intensity (FI) and have optical performance comparable to a top-of-the-line dedicated spectrofluorometer or spectrophotometer. Endpoint, kinetic, spectrum and area-well scanning read types and PathCheck allow homogeneous and heterogeneous microplate assays to be performed in this flexible system. The FI and Abs microplate reader with built-in cuvette port allows easy conversion and optimization of very-low-throughput assays into medium-high-throughput microplate assays. The SpectraMax M2e allows faster, more precise results and reagent savings. In addition, combined absorbance and fluorescence intensity assays can be run by issuing a single read command.
