The SpectraMax® 340 PC 384 Absorbance Microplate Reader from Molecular Devices provides the necessary tools for absorbance measurement in the visible range. Features showcased by this model include temperature control, a robotics-compatible interface and Data Analysis Software.

Every SpectraMax® 340 PC 384 microplate reader has an optical system built around a monochromator. Operators can conveniently select up to six wavelengths at a time for absorbance detection in the visible wavelength range of 340 nm - 850 nm. The narrow bandwidths used by the model increase measurement accuracy and linearity over a wide range of assays. Users can expect high precision and speed when reading 96- and 384-well microplates during endpoint measurements, kinetic assays and spectral scans.

The multichannel optical design of this SpectraMax microplate reader emulates a dual beam spectrophotometer. This unique design allows each sample to be measured directly on the plate. As a result, measurement errors due to variations in light output between optical fibers are eliminated, thus increasing the reliability of the data reported.

Equipped with the patented PathCheck® Path length Measurement Technology, this microplate reader is capable of transforming each microplate well to a fixed optical path length cuvette. Other system attributes include the temperature-independent normalization feature (to correct changing well volumes) and direct concentration calculation based on the absorbance.

The SpectraMax 340 PC 384 Microplate Reader is equipped with Molecular Devices' leading data acquisition and analysis software. Seamless integration StakMax® Microplate Handling System is possible with the Data Acquistion& Analysis Software.
