Our newest multimode microplate reader is a versatile, entry level multimode microplate reader for most common absorbance, turbidimetric, fluorescence, and luminescence microplate assays. Photometric optical design is based on a xenon flash lamp and monochromator for enabling continuous wavelength selection from the UV through the visible range up to 1,000 nm. The broad wavelength ranges enable many common assays including nucleic acid and protein quantification, bacterial growth curves, ELISA, and cell viability.
In Varioskan ALF, fluorescence and luminescence measurements are performed with filter-based optics for optimal specificity and sensitivity. The system comes with three pre-installed excitation and emission filter sets suitable for many common fluorometric applications like Thermo Scientific Quant-IT DNA quantitation assays, PrestoBlue and AlamarBlue cell viability assays. Additionally, five open filter positions are available for customized fluorometric and luminometric measurements. Filter slots are easy to access from the instrument side and no additional tools are required for filter exchange. Also commonly used FRET and BRET assays are easy to set up and perform thanks to Varioskan ALF unique filter-based optics design.
The automatic gain adjustment feature selects the ideal fluorometric or luminometric reading range for your instrument based on signal intensity in the well, eliminating the need to manually adjust measurement parameters. The results are consistent no matter what signals are measured.
