Legacy & Innovation

In the 1970s, the Ligugnana brothers founded International PBI with a mission to revolutionize microbiology. By setting new standards for microbial control in critical sectors—from healthcare to biotechnology—they laid the groundwork for modern contamination safety.

Their pivotal moment came in the 1980s with the patenting of the world’s first handheld air sampler, establishing the global benchmark for monitoring airborne contamination.
