ElectroForce BioDynamic 5900 Test Instrument

The 5900 BioDynamic test instrument accommodates four disc specimens in a single chamber mounted between porous compression platens. The specimens are subjected to axial compression, pulsatile flow through porous platens, and radial cyclic hydrostatic pressure while maintaining sterility in a cell culture incubator. All system components in contact with the samples and the fluid are sterilizable to allow long-term stimulation and characterization in an incubator. Bose BioDynamic test instruments are integrated systems that combine ElectroForce linear motors with environmental technologies and fully-automated computer controls and software. The simple and durable proprietary moving-magnet motor design provides excellent dynamic performance and operates without friction, which is an important feature for high resolution, low force testing. ElectroForce test instruments are controlled by the WinTest digital control system which provides data acquisition, waveform generation and instrument control. Up to 8 actuators can be operated from the same personal computer and up to 32 input channels are available for measurements. This control and software capability allows multi-axial loading to mimic physiologic conditions and data acquisition from multiple sensors.
