The B100 is an entry-level biological compound microscope which emphasizes high-quality optics over mechanical form. All of the necessary functionality is present in an intuitive form factor which is ideally suited for classroom use. The B100 uses a traditional layout which is beneficial for students and other first-time users. The binocular head can be customized for each user, with a sliding interpupillary adjuster for varying eye spacing, and diopters for both eyes to fine-tune focus for nearsighted users and for asymmetry. The head can be rotated 360°, and has a 45° incline for viewing while seated or standing. Interchangeable eyepieces allow for an expanded magnification range, or the use of special eyepieces with pointers and measuring reticles. The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy. The stage is equipped with two clips along with an adjustable limit-stop mechanism that can be used to prevent the lenses from making contact with specimens, preventing damage to the lenses and glass slides. The halogen light-source produces a warmer light which is less fatiguing for the eyes. A rotating Abbe condenser controls the amount of light and contrast. Includes the World of Microscope book for continued learning. Our expanded slide preparation kit is included, with everything you’ll need to create your own specimen slides. Five pre-mounted specimen slides are included for instant viewing and to test your new microscope. Over 50 blank slides and cover slips and a bottle of specialized glass cleaner is provided to clean up immersion oil and stains (not intended for children).
