Developed in collaboration with Mount Sinai Medical Center, the Open Source Hydrostatic Pressure Loader helps researchers cyclically load cell cultures under hydrostatic pressure. As part of Cooper Union's Open Source Laboratory Initiative, the design blueprints are accessible to everyone for free, replacing the need for expensive traditional machines. Most notably, and to the benefit of researchers at both Mount Sinai and Cooper Union, it achieves its goal without requiring the use of an expensive Instron machine. 

The design features an acrylic incubator with a hinged ceiling and/or a front door, and a piston and pressure vessel made from "off-the-shelf" parts.
