Molecular Devices SpectraMax 250 Microplate Reader

Product powers on and works. Includes power cable and a copy of software.

The Molecular Devices SpectraMax 250 Microplate Reader has an optical design that mimics a dual-beam spectrophotometer. Each sample has a discrete sample and reference beam so that each well is measured directly. The eight-channel system consists of 8 sample beams and 8 reference beams, delivering both superior precision and speed of reading across the microplate. The Spectramax 250’s xenon flash lamp and grating monochromator facilitates direct UV measurement of DNA, RNA, and protein in microplates.
