This microscope performs great in any kind of microbiological research: cytological, histological, hematological, and more. Demanding professionals and specialists in different scientific fields appreciate the microscope's possibilities.

The optics provide magnification in a range from 40x to 1000x. Due to the achromatic optics, a transmitted image features high sharpness and contrast. The monocular head is 360° rotatable, a wide-angle eyepiece provides an excellent field of view. Coarse and fine focusing knobs are used for sharpness adjustment.

A microscope stage is equipped with a mechanical scale for precise placing of specimens. There is an Abbe condenser with an iris diaphragm under a stage, and halogen illumination underneath. Illumination features adjustable brightness. It is powered by an AC supply.

Levenhuk 320 BASE can be used for observations using the brightfield research method or oil immersion. All research is conducted in the transmitted light.
