Open Box 40X-2000X 3W LED Siedentopf Binocular Compound Microscope
Key Features
- A heavy-duty, ergonomic microscope for students and professionals.
- Professional features include a Siedentopf binocular head for precise adjustments, a 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.
- Super-bright LED lighting provides cool, daylight-balanced illumination.
- 40X to 2000X achromatically-corrected magnification for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 20X eyepieces provide 8 unique magnification settings.
- This is an open box item and all Open Box items are non-returnable
The B340-LED binocular compound microscope is designed for educational and professional use. The medium-sized profile offers streamlined ergonomics with plenty of working room. The heavy-duty metal build and enamel coating will last for many years through rigorous use.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. 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. The head can also be rotated 360° to accommodate multiple users. Various eyepieces can be used to increase the overall optical magnification.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 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 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. An adjustable height limit can be set to prevent damage to the lenses and specimens while focusing.
The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion height adjustment for precision control.
