Levenhuk 720B – binocular head microscope, an optimal model for use in clinical and medical research laboratories. This instrument will be particularly appreciated by those who conduct in-depth scientific research and work with transparent samples. The Levenhuk 720B microscope is also recommended for home use. Its capabilities will be very useful for students and enthusiasts.
The microscope is equipped with a practical binocular head. Stereoscopic observation is much better for eye health. Long observation sessions will no longer cause discomfort and fatigue. The head is tilted at 45° and rotates around its own axis. The rotation mechanism allows you not to have to turn the entire instrument when you want to share the progress of your research with a colleague.
The Levenhuk 720B microscope is designed for the observation of transparent samples. Applied research methods: brightfield and oil immersion. The kit includes high-quality achromatic objectives and a bottle of immersion oil. The microscope is also equipped with two pairs of interchangeable eyepieces: two Huygens 20x and one pair of 10x eyepieces. The wide range of accessories allows choosing the optimal magnification level and field of view for viewing each specific sample. The total magnification range extends from 40x to 2000x.
The LED illumination is positioned under the stage and features adjustable brightness. The microscope also has an Abbe condenser with an iris diaphragm, which reduces light loss and allows accurate focusing of the light beam on the sample to be observed. The condenser has special centering screws. Sharpness can be adjusted using a single knob, and the focusing system includes coarse and fine adjustment.
The stage allows observation of any chosen sample, even large-sized ones. For detailed study, it is possible to move the stage along both axes, vertical and horizontal, defining a precise working area. Every detail of interest will be clearly visible even at maximum magnification. The stage is also equipped with clips for securing samples.
The Levenhuk 720B microscope features a metal body, which increases product reliability and durability. The kit includes a special dust cover that can also be used for long-term storage of the instrument.

Attention: Refer to the specifications table for the correct mains voltage and never attempt to connect a 110 V device to a 220 V outlet and vice versa without using a converter. Remember that the mains voltage in the United States and Canada is 110 V and 220–240 V in most European countries.
Some of the things that can be observed under the microscope:
The Levenhuk 720B binocular microscope is compatible with Levenhuk digital cameras (sold separately). Levenhuk cameras are installed in the eyepiece tube, in place of an eyepiece.
