Selfrag LAB

The SELFRAG Lab is a laboratory scale solution for selective fragmentation.


The SELFRAG Lab is a laboratory scale solution for selective fragmentation. The Lab uses a SELFRAG high voltage pulse power generator to fragment batches of material and liberate individual components from the whole, whether rock or electronic waste. The Lab is self-contained, compact, and constructed in Switzerland to meet all EU health and safety regulations. The Lab system is ideal for use in geosciences, mining and recycling research.


Self-contained, compact, semi-automated device, designed for installation on level, solid ground in interiors. Constructed in accordance with EU standards.
