M20 - TIRF 3 System Axio Observer (inverted) with incubation

System Description

The M20 system is an inverted widefield microscope for brightfield and fluorescence. It is equipped with temperature, CO2 and humidity control, a motorized xyz-stage, an EMCCD camera and in addition with a motorized TIRF (Total Internal Reflection Fluorescence) insert allowing high resolution visualization of structures within 100nm of the coverslip. All components are controlled by Axiovision. The system is fully programmable and therefore able to run multidimensional experiments including any combination of the following: multiple positions, multiple wavelengths including brightfield (DIC), z-Stacks, time-lapse. Using the TIRF insert is especially useful for visualization of membrane bound components.
