This year marks the 43rd edition of the exhibition, where numerous companies and researchers involved in vacuum technology, including technology development, product manufacturing, and sales, gather annually to engage in business negotiations directly related to their work. Additionally, from November 24 (Wednesday) to December 10 (Friday), 2021, participation is also possible online (free: registration required). We sincerely look forward to your visit.
