Varioskan ALF Multimode Microplate Reader
Manufacturer: Thermo Fisher Scientific
SKU: VA000010C
Description
The Varioskan ALF from Thermo Fisher Scientific is a multimode microplate reader designed for routine laboratory applications. It supports absorbance, turbidimetric, fluorescence, and luminescence detection modes, making it suitable for a range of common assays such as nucleic acid and protein quantification, ELISA, bacterial growth monitoring, and cell viability studies. Its optical system utilizes a xenon flash lamp paired with a monochromator, providing a broad photometric wavelength selection from 200 to 1000 nm. The instrument accommodates various plate formats, including standard 6- to 384-well microplates and specialized Thermo Scientific µDrop Plates. This reader is positioned as an accessible, versatile solution for laboratories requiring reliable performance in fundamental microplate-based analyses.
