A powerful multi-purpose compound microscope for viewing tiny details of specimen slides; excellent for clinicians, high school and university science students, and enthusiastic hobbyists alike.
Professional Siedentopf head is fully rotatable for shared use and equipped with interchangeable wide-field 10X and 25X glass eyepieces fixed at an ergonomic 30 degree tilt to reduce neck strain.
