From SIU-48 to the Future: A Legacy of Innovation
Our journey began with the SIU-48, which was redesigned in 2007 into the smaller, more convenient SIU-24. Today, the SIU-24 is one of the most used device of its kind worldwide, a testament to its performance and reliability.

In 2022, we developed the SIU-14, our smallest model yet, specifically commissioned by a US company from the Research Triangle Region in Durham. This bespoke project highlights our commitment to meeting the diverse needs of our customers.
Responding to evolving needs
Recent inquiries have indicated a growing demand for a slightly larger model. In response, we are excited to announce the development of the SIU-36 under 2025. This new model will be accompanied by a compatible control unit featuring open-source software, ensuring secure functionality and longevity for all our customers.
Our commitment to innovation
We are dedicated to continuously improving and expanding our product line to meet the evolving needs of the research community. With the development of the SIU-36 and its accompanying open-source software, we are confident that we will continue to provide researchers with the tools they need to make ground-breaking discoveries.
