First Hardin Type Resonant Column

With GDS' first Hardin type Resonant Column heading to Australia this month followed by another bound for the USA, the Hardin type cells are proving popular with our customers.

Having sold over fifty of the Stokoe cell types, these are the first hardin type systems to be sold by GDS. The Hardin type Resonant Column apparatus (H-RCA) is a system that allows samples to be tested in resonance while maintaining an anisotropic loading. This is achieved by a slender, thin walled loading column passing through the drive system to the topcap.

The Hardin style oscillator contains an electro-magnetic drive system incorporating precision wound coils and composite sintered neodymium iron boron (NdFeB) “rare-earth” magnets. The apparatus can be mounted in a stand-alone system with an integral axial force actuator or as a cell for integration into an existing loadframe. A high pressure version of the standard cell is set to be released next year which will be heading out to a university in Canada.
