Quick release Core Holder LEQRC series

The LEQRC Series are Hassler type core holders which permit loading without complete core holder disassembly; achieved via an innovative ¼ turn, fast-release bayonet mechanism. Another convenient characteristic of the QRC series core holder is that the sleeve remains inside the core holder; the core is loaded from one end without the need of filling/draining the confining fluid.

By releasing the confining pressure and unscrewing the end plug, the core sample can easily be removed without exposure to the hydraulic fluid, i.e. nitrogen or hydraulic oil. This avoids assembly/disassembly-related sleeve damage. Furthermore, experimental preparation is much faster and easier; therefore these vessels are particularly suited for low pressure, short duration experiments.
