The CKX41 inverted microscope with trinocular head options and fluorescence upgrade capability is suitable for advanced techniques such as the imaging of GFP and other fluorescence applications. The high-angle tilting head allows quick and easy visual checks, while advanced UIS2 optics produce outstanding images. Visibility is further increased with Olympus relief contrast, particularly when using non-glass cell culture vessels, and productivity is increased with pre-centred phase contrast. Digital cameras can be connected for efficient documentation tasks and archiving.
