Very serious binocular laboratory microscope from Zeiss! Although this unit, with serial 289187 dates back, it looks literally brand-new. WOW! Has a quad turret with four lenses on it. The entire kit comes with much more gear. Bunches more ocular lenses, prep glass, etc. etc. Has a very complex adjustable stage, variable condenser, and two-sided mirror. It doesn’t even have a speck of dust on it… Comes in a wooden case, which will delight you! 7.5” x 5” x 14”, weighs 14.6 lbs. This is the cream of our current crop.
