Zeiss Axio Observer A1 Inverted Phase Contrast Fluorescence Microscope.

Zeiss Axio Observer A1 Inverted Phase Contrast Fluorescence Binocular Microscope (Catalog Number: 431004)

The Zeiss Axio Observer A1 is a reliable, manually operated inverted fluorescence microscope built for routine cell culture, phase contrast imaging, and fluorescence applications in research and academic environments. Equipped with Zeiss infinity-corrected optics and designed for long-term stability, the Observer A1 provides sharp contrast, high image quality, and robust performance for live-cell and fixed-sample imaging.

This system features a binocular viewing head, which is standard on the A1 model, as well as a manual focus drive, manual filter turret, and a manual stage (with optional motorized stage upgrade available). It is fluorescence-capable and well-suited for DAPI, FITC, TRITC, and other standard fluorophores.
