As the microscope that sets the standard for high school instruction, the 128-CLED is part of a series of compound microscopes that include all of the most commonly specified features like rugged metal construction and locked-on parts. The superior DIN optical system and precision mechanical components assure sharp, unsurpassed viewing. Dual view head allows teachers to observe simultaneously what students are viewing, or enables two students to view specimen at the same time. This microscope is recommended for instruction through grade 12.
Superior DIN optical system combined with LED illumination…delivers higher light efficiency than standard 20 watt tungsten bulb and assures cool operating temperature. Dual viewing head permits simultaneous viewing by student and teacher, and is also ideal for video microscopy. A very versatile microscope recommended for instruction through grade 12.
