Abstract
A centrifuge housing has a lid with a hinge with two hinge parts and a horizontal hinge axis. The lid is able to rotate between a closed position, in which the lid's centre of gravity is positioned on one side of a vertical plane through the hinge axis, and a fully opened position, in which the centre of gravity is positioned on the other side of the vertical plane. A longitudinal spring is connected to a connection member for urging it longitudinally. The connection member is connected at a hinge point at a distance from the hinge axis. The spring assists raising the lid initially during opening and closing the lid initially during closing from the fully opened position. The lid has a position of stable equilibrium in an intermediate position between the closed position and a vertical position.
