The B270 series delivers an advanced binocular compound microscope designed for most student or professional applications. With its protective antimicrobial coating, enhanced LED lighting, Siedentopf head adjustments, quadruple turret with four plan objectives, coaxial coarse and fine focus, this microscope is an ideal solution for any laboratory or classroom facility.

Microbe-Resistant Protection

Developed with a protective microbe-resistant coating, the B270 series microscope utilizes a revolutionary paint treatment that works to restrict the growth of microorganisms, including bacteria and mold, which makes it an ideal solution for any laboratory environment.

Viewing Head

The B270 series compound microscope is designed with a Siedentopf binocular head. To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted by simply swiveling the eyepieces. A diopter is available on the left ocular tube to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain. Various eyepieces can be used to increase the overall optical magnification.

Optics

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.

Stage

The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.

Transmitted Illumination

The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. With our specially developed fly-eye lens, the light is evenly distributed at maximum brightness to improve contrast and resolution. Illumination is further enhanced by a centerable Abbe condenser, which can be realigned for any magnification to guarantee proper lighting.

Security

Protect your investment by using the premium microscope lock with key. The B270 microscope incorporates the use of a microscope lock that acts as a theft deterrent, discouraging to casual thieves.
