The Eisco Labs Hydraulic Press features high-quality borosilicate graduated cylinders mounted on a metal frame. The model demonstrates how fluid pressure works within interconnected cylinders of different sizes. The smallest cylinder includes a petcock to control air flow. Students can observe Pascal’s principle in action — pressure applied to the small cylinder is transmitted equally to the larger cylinder, producing a mechanical advantage. Suitable for physics classrooms studying fluid mechanics, pressure, and hydraulic systems.
