Overview
Not a low-power stereo scope, this is a compound microscope with a rotating Siedentopf binocular head and two interchangeable eyepiece pairs. Four achromatic objectives sit on a forward-facing nosepiece above a double-layer mechanical stage.
Two eyepiece pairs widen the magnification options without extra objectives, and the oil objective brings in the highest power. The listing is inconsistent on power source and body material, so check those details before counting on cordless use.
Who it's for
A science class, a homeschool lab or an advanced hobbyist can swap eyepieces to match the specimen. Anyone who must work away from an outlet should verify the power details first, and anyone handling large objects wants a stereo scope.
Pros and cons
- Two eyepiece pairs give eight magnifications
- Spring-loaded high-power objectives protect slides
- Head rotates for shared viewing
- Mechanical stage with coordinate divisions
- Power source data conflicts in the listing
- Body material data conflicts in the listing
- Oil needed for the highest power
- Weight and size not listed
Performance notes
Switching between the two eyepiece pairs changes the power of each objective, which is how eight combined magnifications come from four objectives. Brightfield lighting passes light through the slide, so stained or translucent samples show best, and the condenser iris tunes contrast. The LED source runs cool, which suits live specimens.

Frequently asked questions
What is included with the AmScope B120B?
The listing has no package contents line. The description names a binocular head with two interchangeable eyepiece pairs, four objectives on a nosepiece, an Abbe condenser with iris and a double-layer mechanical stage. Immersion oil and a dust cover are not named for this model.
Is the AmScope B120B battery powered?
The spec line says battery powered, while the description gives 100 to 240VAC 50/60Hz. The two conflict, so confirm the power source before relying on cordless use.
Is the AmScope B120B a stereo microscope?
No. It is a compound microscope with achromatic objectives for slides, not a low-power stereo scope for handling larger objects.
