The Olympus CX43 Biological Binocular LED Upright Microscope enables users to remain comfortable during long periods of routine microscopy observations. The frame conforms to the user’s hands and the location of the control knobs maximise ergonomics to improve work efficiency.

Users can quickly set a specimen with one hand, while adjusting the focus and operating the stage with the other hand with minimal movement.

The CX43 can be equipped to handle a range of techniques, including phase contrast, darkfield and simple epi-fluorescence.
