The new Piuma Nanoindenter

 

Optimized for benchtop use

The Piuma Nanoindenter is designed to operate as a stand-alone instrument in any lab setting. Amongst many applications possible, the Piuma can be used to perform comparative studies on biological samples such as cartilage, dermis or cornea, optimize and select between polymer or hydrogel synthesis or crosslinking procedures or define material performance parameters such as surface adhesion, swelling or degradation, also in liquids.

 

Piuma features

Easy operation due to the built-in camera (top-view, 5X) and the coarse manual Z-stage. Almost any sample size or shape can be used thanks to the large sample stage. Optionally a sample stage heater is available (from room temperature up to 60oC), a back light illumination module, an inverted camera module for small or transparent samples and an acrylic housing for use in more noisy environments.

 

Instrument versions

Even the most basic instrument version is well equipped, featuring an automated find-surface procedure, fully motorized 12x12x12mm X-Y-Z stages for automated force mapping and many more. Our standard instrument version features a displacement controlled mode of operation, enabling force-displacement experiments of any sample without needing any prior knowledge. On top of this our dynamic module expands the functionality with load-, indentation-, and frequency controlled modes of operation.
