Perfect for classroom settings, the Swift M2250 Series microscopes are both durable and cost-effective solutions for your needs. There are lots of features here which essentially "studentproof" the units from tampering or theft, such as locked-on parts and a slip clutch which helps avoid gear damage.
The M2251F is the model with fluorescent illumination, featuring supremely bright lighting which has a cool 6400 Kelvin temperature for accurate color reproduction. Fluorescent light emits practically no heat compared to standard tungsten bulbs, as well as having an enormous 10,000-hour lifespan and electric efficiency. The bulb can be easily replaced.
