Used to measure compressive strength of gypsum material that was eroded in some experiments. In the Carleton Laboratory of Columbia University, carelton.columbia.edu.
From Carleton lab description:

The Instron 600DX 135k UTM is a load and displacement controlled hydraulic testing machine. The Bluehill 3 control system allows this machine to fulfill a wide array of duties, ranging from undergraduate and graduate teaching, independent research, doctoral research, to high-volume testing of medium-sized high-strength materials. Along with its higher-capacity neighbor, the 600DX is equipped with a presentation LCD, which allows the machine to display live results of ongoing testing.
The system is designed with dual test spaces for tension, compression, bend, shear, and flexure testing on high strength materials.
