Medium Stoppering R&D Freeze Dryer – QualiRFD™ 8S
A Freeze Dryer with vial stoppering helps R&D teams develop cycles that stay stable after drying and during storage. The QualiRFD™ 8S Freeze Dryer is designed for medium-scale development batches where process repeatability and production-like handling matter. It runs an in-situ workflow, so freezing and drying occur inside the same chamber to reduce handling steps and improve consistency across trials.
QualiRFD™ 8S is an in-situ vacuum Freeze Dryer built around a dual-chamber layout that combines a drying chamber with a cold trap (condenser). The cold trap captures sublimated vapor efficiently while the chamber stays under controlled vacuum, supporting stable primary drying conditions. A stoppering function seals vial stoppers after the cycle, which helps reduce moisture uptake and contamination risk during storage and transfer.
The control platform supports recipe-based operation with multi-step segments, so teams can develop, save, and repeat temperature ramps and holds while optimizing cycles. Shelf-level sample temperature probing supports better visibility during cycle development and troubleshooting when product temperature limits are tight.
