From March 24 (Tuesday) to March 27 (Friday), 2026, RheaVita will exhibit as a conference sponsor at ISLFD, held in Fukuoka, in collaboration with Lifix Analytical. ISLFD is an international conference where researchers and engineers involved in freeze-drying and related technologies gather from around the world to exchange information and discuss research results and technological trends. Through our sponsorship at this conference, RheaVita will present the latest information on spin freeze-drying technology. At our booth, in addition to introducing the latest information about spin freeze-dryers, we will be open to consultations on a wide range of topics, including research and development, feasibility testing, scaling up, and comparisons with existing processes. We aim to create a valuable platform for information exchange for those asking questions such as "What is spin freeze-drying?", "What are the differences from conventional freeze-drying processes?", "What are the challenges of scaling up and reproducibility?", and "What new formulation and manufacturing approaches should be considered?". Additionally, individual meetings will be possible during the conference. If you contact us in advance, we will secure a meeting opportunity at a time that is convenient for you. Please be sure to stop by the RheaVita booth.
