The SpectraMax 190 Microplate Reader from Molecular Devices is ideal for UV-Vis life science applications, especially DNA analysis. The multi-channel design truly mimics a dual-beam spectrophotometer. Each sample has a discrete sample beam and reference beam so that each well is measured directly, eliminating error due to variations in light output between the optic fibers. The system consists of eight sample beams and detectors and eight reference beams and detectors to deliver both superior precision and speed-of-reading across the microplate through 4.0 OD. Optional tools for verifying the SpectraMax 190 reader performance include the SpectraTest ABS1 Absorbance Plate and IQ/OQ/PQ manual. Software tools for regulatory compliance, such as FDA 21 CFR Part 11, are available through SoftMax Pro GxP Software.
