The Xpose is a microvolume spectrometer for high-speed quantification of one to 16 nucleic acid or protein samples. The full-color touch screen gives access to analytical software, including dye-free specific quantification of DNA, RNA, or protein in samples containing interfering components, using algorithms for UV/VIS spectral deconvolution. Full UV/VIS spectral optics are combined with the microfluidic properties of the Xpose slides for biomolecule quantification in volumes as low as 2 µL. The slides can also protect samples from evaporation, allowing preparation and storage of samples for up to two hours prior to read-out.
