MAGUS Bio 250TL (SKU: 82891) is a biological microscope for observing thin sections and smears of preparations in transmitted light using the bright field technique. Equipped with an optical system with planar-achromatic objectives with infinity correction and a 3 W LED lamp, it provides high image quality and work comfort. The microscope can be expanded with accessories for phase contrast, dark field and polarization, making it a versatile tool for laboratories, research and education.
