Our mission is simple; to be TRUSTED by educators, researchers, and scientists throughout the world to design, manufacture, and DELIVER products that allow LEARNING and the development of scientific knowledge. It has been said that if you tipped a chemistry classroom upside down, everything that falls out that is not a chemical is a product we manufacture. That includes beakers, burners, tongs, and anything made of glass, plastic, metal, ceramic or cork. Whether you are studying forces and motion or Schrödinger’s wave equation, we have the apparatus and experiments you need to study those topics and everything in between. Our product line ranges from hundreds of anatomical models, to dissecting equipment, to microscopes and slides. Our mission is simple; to be TRUSTED by educators, researchers, and scientists throughout the world to design, manufacture, and DELIVER products that allow LEARNING and the development of scientific knowledge. For over 50 years, Eisco Scientific has been manufacturing and selling quality science equipment and supplies worldwide. Eisco Scientific is a multinational corporation, providing products to academic and industrial customers in over 100 countries. The Eisco Industrial division has been created to focus on the needs of industrial and academic research laboratories.
