Levenhuk MED 25B Binocular Microscope - LEVENHUK
The Levenhuk MED 25B microscope is a binocular model equipped with two condensers, one for bright field and one for dark field. Both condensers can be used for oil immersion observations. The microscope is designed for professional use in medical, microbiological, biochemical and other scientific fields. It can be used for research, diagnostics or educational activities. This microscope allows you to perform observations with magnifications up to 1000x, can be configured with Köhler illumination and allows you to study the complicated details of microscopic structures.

This microscope allows you to perform observations with magnifications up to 1000x, can be configured with Köhler illumination and allows you to study the complicated details of microscopic structures.
The trinocular head can be rotated 360°. The eyepiece tube is inclined at 30° to make prolonged observations more comfortably. The kit includes wide-field eyepieces with 10x magnification. They are equipped with diopter adjustment, so as to individually compensate for the observer's visual defects. The nosepiece contains four planachromatic objective lenses; which provide an aberration-free image, the 100x objective allows oil immersion observations. Two of the lenses are equipped with a protective spring mechanism. The optics of all accessories have undergone an anti-mold treatment.
The samples are positioned on the stage with the help of a mechanical translator. The double layer table can be moved along two axes. Sharpness adjustment is achieved by rotating the two fine or coarse focus adjustment knobs. The pitch of the mechanism is very small and allows for smooth adjustment of sharpness. The samples are illuminated from below by a 20 W halogen lamp. The illumination system allows adjustment of brightness. The light passes through an Abbe condenser with an iris diaphragm, on which filters can be installed (three filters are included in the kit). Additionally, a dark field condenser can be installed on the microscope. It is also included in the kit and is suitable for use with oil immersion.
The lighting is powered by the AC mains.

Attention: strong>
Refer to the specification table for the correct mains voltage and never attempt to plug a 110V device into a 220V outlet, or vice versa, without using a transformer. Please note that the mains voltage in the United States and Canada is 110 V and is 220–240 V in most European countries.
Some of the things you may observe under the microscope:
The Levenhuk MED 25B binocular microscope is compatible with Levenhuk digital cameras (purchased separately). Levenhuk cameras are installed in the eyepiece tube, in place of an eyepiece.
