Small Stoppering R&D Freeze Dryer – QualiRFD™ 6S
A Freeze Dryer for stoppered vials helps you develop cycles that stay stable after drying and during storage. The QualiRFD™ 6S Freeze Dryer is a pilot R&D unit designed for vial-based lyophilization with an integrated stoppering mechanism.
This format supports process exploration that is closer to production practice, while keeping batch sizes practical for development work. The system runs an in-situ workflow where freezing and drying occur inside the same chamber, which reduces handling steps and supports repeatable runs.
QualiRFD™ 6S is an in-situ vacuum Freeze Dryer built around a dual-chamber layout that includes a drying chamber and a cold trap (condenser). The condenser captures sublimated vapor efficiently while the chamber stays under controlled vacuum.
A stoppering function seals vial stoppers after drying, which helps reduce moisture reabsorption and lowers contamination risk during storage and transport. The control system supports recipe-based operation for cycle development, with the ability to store many programs and run multi-step temperature segments.
