"The Piuma opened a new world for us."

"We now are able to perform measurements on very low stiffness tissues, with a precision that allows us to study embryos. Colleagues are impressed and come with other challenges that the Piuma easily meets."

Prof. dr. ir. Theo Smit
Dept. Orthopedic Surgery, VU University Medical Centre Amsterdam, The Netherlands

"I am currently writing a paper with the Piuma"

"Our data are good, but the machine is excellent!"

Univ.-Prof. Dr. Werner E. G. Müller
Institut für Physiologische Chemie, Universitat Mainz, Germany

"Powerful, reliable, and use-friendly"

"The Piuma is a very powerful, reliable, and use-friendly instrument to assess the mechanical properties of both living tissue (eg. tissue explants) and in vitro developing engineered tissue. Furthermore, due to the possibility to perform non-destructive mechanical testing, I found PIUMA a very powerful instrument to follow-up mechanical properties of growing in-vitro tissues, giving the possibility to study tissue evolution over culture time."

Francesco Urciuolo, PhD
Research Technologist at Instituto Italiano Tecnologia, Napli, Italy
