The Zeiss Cell Observer is a widefield fluorescence microscope system which allows you to visualize living organisms and intracellular processes, even over a period of several days, involving a number of different fluorescence channels, z-planes and positions. For long term imaging of cells the microscope is housed within an environmental chamber and has heated stage inserts providing precise control of temperature, CO2 and humidity. The objective lenses have been specially designed for live cell Imaging, including correction rings to avoid spherical aberration when imaging between 23-37C. This system can image multiple types of culture dishes including 6 well plates with the motorised stage allowing image capture from multiple points in each well in turn.
