Molecular Devices SpectraMax Plus Microplate reader

The standard for UV-visible microplate reader absorbance, providing ultrafast,
full spectral range detection for cuvettes and 96-well microplates,
with the only temperature-independent method for pathlength correction.

The optical system of SpectraMax Plus Microplate Reader is built around a monochromator,
which allows for selection of up to six wavelengths at a time for absorbance
detection in the UV-visible wavelength range (190 nm - 1000 nm).
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® Pathlength Measurement Technology,
the SpectraMax Plus Microplate Reader transforms each well in a microplate to a fixed optical path length cuvette.
This temperature-independent normalization corrects for varying well volumes
and can eliminate standard curves by allowing the calculation of concentrations directly
from the absorbance with a known extinction coefficient, as exemplified with nucleic acid and protein quantification.
