The breakforce machine at NIOZ is a customized MultiTest dV- precision tension and compression tester. This machine is used to measure the force that is needed to break the shells of bivalves and gastropods. The device works by placing a mollusc between two plates, after which the upper plate is gently and automatically lowered until the shell crushes. The device measures the maximum exerted force to crush a shell in Newton. The generated data is used, for instance, to understand prey choice in birds (birds like red knots crush the shells in their gizzards) or to measure if parasites have an affect on the shell armour of their host.
