Varioskan Flash Reader

The Thermo Scientific Varioskan Flash Spectral Scanning Multimode Reader is a highly flexible plate reader capable of handling fluorometric (excitation/emission), luminometric (emission) and photometric (absorbance) measurements in 96+ well format. The Varioskan can handle a broad range of applications from reporter assays to FRET. The Varioskan is equipped with three on board fluid dispensers, incubator and shaker to allow for real time assays. Coupled with the Tecan EVO, the Varioskan should allow major improvements in high throughput experiment design. Currently the Varioskan is located in 68-252d. Please speak with Linsday Julien about training if you wish to use the machine.
