The Biotek PowerWave XS is a single-channel, automated, benchtop, and general-purpose absorbance microplate reader that performs optical density measurements of samples in a 6-, 12-, 24-, 48-, 96- or 384-well microplate format. The PowerWave XS features a monochromator which offers continuous wavelength selection from 200 to 999 nm in 1-nm increments, as well as wavelength scanning without the need for interference filters. A variety of read methods can be utilized, including endpoint, kinetic, multiwavelength, and spectral scanning. This microplate reader also offers superior absorbance optical specifications, with an extended dynamic range of up to 4.000 OD. The user may choose from three reading speeds: normal, rapid, and the ultra fast sweep mode. The microplate reader is computer controlled using Biotek's Gen5 PC software for all operations, including data reduction and analysis.
Absorbance measurements are made by utilizing the featured xenon flash lamp and the monochromator for wavelength selection. The PowerWave XS is also equipped a unique 4-Zone temperature control from 4°C over ambient to 50°C that ensures superior temperature uniformity necessary for kinetic assays. An internal microplate shaker is also featured on this unit, which allows for selection between low, medium, high, and variable speeds with adjustable durations all programmable by the user. The PowerWave XS can also be interfaced with Biotek's BioStack Microplate Stacker for robotic functionality. Common applications this microplate reader is used for includes: ELISA assays, kinetic enzyme assays, nucleic acid quantitation, protein analysis, and much more.
