Levenhuk 400B is a binocular laboratory microscope for professional work for a microbiologist, medical worker, veterinarian, ornithologist, ecologist, or biochemist. This universal model can be used for bright field research as well as for research using oil immersion. This microscope features a reliable metal body, high-quality achromatic optics and bright LED light with a collector.

A binocular head is optimal for lengthy work with a microscope as it reduces eyestrain. It can be rotated 360° around its axis; a visual part is inclined at 30°. Wide-field eyepieces provide 10x magnification; achromatic objectives come pre-installed in a revolving nosepiece: they provide 4x, 10x, 40x, and 100x magnification. Total microscope magnification varies in the range from 40x to 1000x. The 40xs and 100xs objectives are equipped with protective spring-loaded frames of the front lens. A 100xs objective can be used for oil immersion.

The stage is equipped with a mechanical scale; under the stage there is an Abbe condenser with an iris diaphragm and a filter holder. Below, there is a lighting unit: an LED light with a collector. The light brightness is adjustable. Due to rechargeable batteries (included), this microscope can be used without a power supply.
