Our most popular classroom compound microscope, the Zeiss Primo Star moves famous Zeiss optics into an affordable package so even students can see things clearly. Designed with a compact footprint and form factor, it can often fit into older cabinets where many bulkier models will not fit. Brass focus gears and stainless steel rack and pinion stage mean that these microscopes are built to last. Standard with LED illumination so you can forget about halogen bulb changes! Freely swap to included halogen if that is your preference. Integrates easily into our digital classroom concept.
