Euromex BioBlue Monocular Microscope – BB.4200 (High‑Quality Optical School Microscope)

The Euromex BioBlue Monocular Microscope BB.4200 is a high‑performance optical microscope designed for precision, ease of use, and long‑lasting reliability in school and college laboratories. Featuring a DIN WF 10x/18 wide‑field eyepiece and achromatic semiplan 45mm DIN objectives, this microscope delivers exceptional clarity, maintaining focus and image alignment even when changing magnification.

The high‑precision coaxial coarse and fine focusing system, combined with spherical‑corrected optics, ensures sharp, detailed images suitable for biological studies at all curriculum levels. A height‑adjustable Abbe condenser (N.A. 1.25) with iris diaphragm and filter holder provides excellent illumination control for a wide variety of specimens.

Built with a strong, stable aluminium BioBlue stand, this model includes a built‑in protection system to prevent accidental damage to slides or objectives. The BB.4200 version features a plain stage with two object clamps, while other models in the BioBlue range include mechanical X‑Y stages.

LED Illumination System

The BioBlue microscope features a powerful 1‑watt adjustable LED illuminator that produces bright, even lighting with no heat output. With an internal universal AC power supply and built‑in rechargeable NiMH AA batteries, the microscope can operate continuously for up to 60 hours without external adaptors—ideal for portable use between classrooms.

Ergonomic & Durable Design

The BioBlue has been carefully designed with ergonomic features to support long microscopy sessions. Comfortable adjustment knobs reduce student fatigue, while the modern stand design and built‑in handgrip make the microscope easy to transport and safe to handle. The robust aluminium construction ensures long‑term reliability in busy school environments.
