Molecular Devices Spectramax 190 Absorbance Microplate Reader

Description

Molecular Devices SpectraMax 190 Microplate Reader

The Molecular Devices SpectraMax 190 Absorbance Microplate Reader mimics a dual-beam spectrophotometer and measures each sample in the plate directly. Using this method eliminates measurement error due to variations in light output between optical fibers.  As a result, users get more reliable data reporting. The eight-channel system of this plate reader delivers both high precision and speed when reading 96-well microplates for endpoint measurements, kinetic assays, and spectral scans.

The SpectraMax 190’s optical system is built around a monochromator, which allows for the selection of up to six wavelengths at a time for absorbance detection in the UV-visible wavelength range (190 nm—850 nm). The Narrow bandwidths deliver increased measurement accuracy and linearity over the widest range of assays, including DNA quantitation in the UV range. Using the patented PathCheck Path length Measurement Technology, this plate reader transforms each well in a microplate to a fixed optical path length cuvette.

This temperature-independent normalization corrects for varying well volumes. It can eliminate standard curves by allowing the calculation of concentrations directly from the absorbance with a known extinction coefficient, as exemplified by nucleic acid and protein quantitation.  The SpectraMax 190 is supplied with SoftMax Pro Data Acquisition & Analysis Software, Molecular Devices’ industry-leading all-in-one data acquisition and analysis software. Additionally, the system can be seamlessly integrated with the StakMax Microplate Handling System through the SoftMax Pro Software.
