The Levenhuk MED 20B binocular microscope is designed for professional microcosm research with magnifications from 40 to 1000x. It has semi-planachromatic lenses that minimize chromatic aberrations and significantly flatten the curvature of the field of view. This microscope is an excellent purchase for the microbiology department, medical laboratory, or research institute.
The binocular head is perfect for long observations because it allows viewing through the microscope with both eyes. The viewing part is inclined at a 30° angle. The trinocular head rotates 360°, a useful feature for group research.
The wide-field eyepieces provide 10x magnification and allow diopter adjustment to achieve the sharpest possible image. Coarse and fine focusing controls enable image sharpness adjustment. Both focusing systems have fine-threaded pitch and allow setting the microscope for complicated observations. A revolving nosepiece contains four objectives. The 40x and 100x objectives are equipped with spring mounts. The 100x objective is intended for oil immersion observations (a bottle of immersion oil is included in the kit). The eyepieces and objectives are coated with an antifungal layer.
The double-layer mechanical stage features a graduated scale. The illumination system includes a lower light source and an Abbe condenser with an iris diaphragm and a filter holder. A 20 W halogen lamp is used as the light source. The brightness of the light is adjustable. The light is powered by an AC power supply. Additionally, the microscope allows setting Köhler illumination.

Attention:
For information regarding correct mains voltage, consult the specifications table. Never attempt to connect a 110 V device to a 220 V power outlet or vice versa without using a voltage converter. Note that mains voltage is 220–240 V in most European countries and 110 V in the United States and Canada.
