Welcome

GDJ was founded by a former educator whose main goal is to bring math and science from theory into hands-on practice. To accomplish this GDJ is providing interesting laboratory equipment designed to capture the student’s interest.

GDJ has built a reputation for innovative highly accurate lab equipment at practical prices. American made, and currently in use in leading universities, NASA labs, and industrial testing facilities throughout North America. Complete classroom curriculum modules, developed by educators, combine the impact of "hands-on" learning with the accuracy and methodologies of true laboratory-grade test equipment.
