Our LSR-Fortessas are 4/5 laser, 18 colour machines. We use saline as a sheath fluid, which is in 20 litre ‘FACSFlow’ boxes under the benches behind the machine. The Fortessas run at the same speed with the same software as the CantoII, but has the fluidics system of the FACSCalbur.
The Fortessas are the best cytometers we have for measuring yellow excited flourochromes such as mCherry and Alexa568.
Complete Optical Configuration of the Fortessa1
Our second Fortessa has exactly the same configuration as our first fortessa on the violet, yellow and red laser paths, but a different configuration on the blue laser and the addition of 2 channels on Ultra-Violet 355nm
