Description
Two better-quality microscopes for high school. Both have the following features:
Model 3000F features stage with 0.65 N.A. condenser with 5 hole disc diaphragm. Model 3000F-100 adds a fourth objective (a 100X retractable oil immersion lens which yields a 1000X magnification) and a mechanical stage with 1.25 abbe condenser iris diaphragm. The mechanical stage allows horizontal movement of the specimen in both X and Y directions in 0.1 mm graduations and features spring loading for exact positioning of the specimen.
Due to a change by the manufacturer, fluorescent light sources have been phased out and now all 3000F models feature LED light sources. Models ending in LED are corded models and those ending in RC are cordless rechargeable and include an AC adapter. Replacement bulbs are available for LED models and previous models; please note that if you purchased your LED model after 9/09 it is probably the snap-in type (but check your existing bulb assembly to make sure). These models have a limited 5-year warranty.
