Cool performance -These high school microscopes have fluorescent illumination that radiates little or no heat compared to lower-priced models with tungsten illumination—a very important benefit when you’re working with live microorganisms. Fluorescent light is also whiter and promotes longer bulb life. The focus mechanism has separate coarse and fine adjustments, incorporating travel stops and a slip clutch to protect slide, objectives, and focus mechanism. Cool options - Choose between models with a stage that is predrilled for an optional add-on mechanical stage, or models with a built-in mechanical stage for smoother slide positioning. Cool value - Get the features you need, including an inclined and rotatable head, in-base illuminator, and disc or iris diaphragm, at affordable prices. Quality DIN** optics include a widefield 10× pointer eyepiece and 40× and 100× objectives that retract to prevent possible slide damage. Locked-on eyepiece and stage clips protect against loss and tampering. Each microscope comes with dust cover and foam case. Five different configurations are available. Size, 14″ H × 5″ W × 6½″ D; weight, about 7 lbs.
