FreeZone Stoppering Tray Dryers provide precise control and program flexibility for consistent performance and are designed for lyophilizing moderate to large loads and stoppering vials or serum bottles under vacuum. They offer options for a built-in 6-port manifold and isolation valve.

• Compact design for moderate to large sample loads or numerous sample batches
• Precision with 3 temperature-controlled stoppering shelves between -40 and +40 °C
• Flexibility with temperature and vacuum level control
• Quality reassurance with onboard data collection, and real time graphing
• Sample probes with remote notification of operating parameters or alerts

The chamber pre-freezes samples to save time and money by eliminating the need for a separate freezer and product transfer

Three 16.5" x 12" temperature-controlled (±1 °C), adjustable shelves with sample temperature sensors provide up to 594 sq. inches of shelf space. Circulating fluid in shelves ranges from -40 and +40 °C and features an environmentally-friendly HCFC/CFC-free refrigeration system. A clear acrylic viewing door provides complete visibility of the shelves. The ¹/₈" OD backfill port introduces sterile air or inert gas from an outside source to the chamber, protecting samples from atmospheric moisture and contaminants.

Lyo-Works™ OS provides a real time display of freeze dryer and tray dryer parameters on a 5" full color touch screen on the connected FreeZone 6, 12, or 18 Liter Freeze Dryer (sold separately). Data may be exported via USB or Ethernet. A microprocessor-based controller allows up to 30 different temperature programs to be stored and repeated, each using up to 16 different steps. The display provides navigation to manual or program mode, probe temperatures, vacuum in mBar, Torr or Pa, step of the program in progress, time remaining in present step, and end of program, as well as alarms. Alerts and current operating parameter reading can be sent automatically to user-entered email addresses.

Optional 6-Port Tray Dryer Manifold accommodates either ¹/₂" or ³/₄" flask adapters and connect to flasks and other glassware. The optional built-in isolation valve separates the Stoppering Tray Dryer from the freeze dryer to shorten time necessary to reestablish working vacuum levels and to provide a means for determining end point.
