"A 200 g centrifuge was donated to the Carleton Laboratory by the Kajima Corporation in 2004 and is currently used in a wide array of geotechnical research fields, ranging from slope failure analysis, levy failure, lateral loading of pile foundations, saturation experiments, etc. The large payload capacity and high acceleration rating makes this centrifuge an incredibly versatile and flexible piece of equipment."

The centrifuge was used for enhanced-G granular flow experiments by a team at Columbia, led by Colin Stark.
