Overview

Piuma is a revolutionary product that is simple and easy to use. Piuma's histopathological and mechanical analysis of biological tissues brings hope for micro - and nano level research on soft matter and biomaterial tissues. Relying on the new optical technology and outstanding micro processing technology developed by itself, the viscoelastic measurement of Piuma biological tissue hydrogel can measure the samples with the softest Young's modulus, even ranging from 5Pa to 5GPa! Piuma is also very suitable for testing samples in liquids. Its operation is very simple and easy to learn. Simply insert the probe into the instrument, calibrate it briefly, and start the indentation experiment immediately.

Product Details

Optics10 was founded in 2011 and is a spin off organization of the Free University of Amsterdam (VU). Since then, the revenue and employees of this startup have continued to grow, becoming one of the fastest-growing companies in the Netherlands and having international influence.

Fiber On Top probe

The new fiber optic interferometric cantilever beam probe uses an interferometer to monitor the deformation of the cantilever beam.

Compared to atomic force microscopy or traditional nanoindentation instruments

The innovative fiber optic probe compensates for the problem of traditional nanoindentation instruments being unable to test soft materials, and also solves the common defects of AFM in mechanical testing, such as large fluctuations, difficult operation, and strict sample preparation.

●Low background noise: Laser interferometer has stronger anti-interference ability than AFM reflection path

●Simpler sample preparation: higher tolerance for sample roughness than AFM

●More accurate stiffness selection: The parallel cantilever beam structure is conducive to accurately distinguishing the proportional relationship between indentation depth and piezoelectric ceramic displacement, facilitating the selection of appropriate stiffness probes to ensure the stability of elastic deformation relationships, and thus obtaining data with higher repeatability and better accuracy

Built in analysis software

●With the help of functional and easy-to-use software, users can freely operate itControl the indentation program (load, displacement, etc.). The process of automatically processing curves enables rapid analysis of data and results

●Export the original parameters in complete txt format for the convenience of subsequent complex processing needs

●Using the Hertz contact model to calculate the elastic modulus from the loading section is more suitable for the characteristics of biological tissues and soft material materials compared to the commonly used Oliver&Harr method
