Committed to the concept of continuously improving its models, Motic’s Elite series microscopes represent Motic’s most advanced models. Featuring Motic’s Infinity Optical System and the improved CCIS EC Plan objective lenses, the BA310 Elite provides superior image clarity and contrast. The elite models introduce a new rackless stage concept without a prominent gear rack which allows even more convenient use of the X/Y movement. The elite models also allow easy interchangeability of its 6V/30W Halogen bulb with LED modules.
