FreeZone Stoppering Tray Dryers 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. The chamber pre-freezes samples to save time and money by eliminating the need for a separate freezer and product transfer. Built-in pneumatic mechanism stoppers containers on all three shelves.
The Stoppering Tray Dryers feature a brushed stainless steel and glacier white, powder-coated steel exterior, integral support stand and side-mounted power switch. They include three 16.5" x 12" adjustable shelves and temperature sensor probes to monitor sample or shelf temperature. A clear acrylic viewing door provides complete visibility of the shelves.
A single 1 hp HCFC/CFC-free refrigeration system and 1000-watt electric heater cool and heat the fluid medium circulating through channels in the shelves. The temperature may be set between -40 and +40°C. 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, capacitive touchscreen 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.
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.
Freeze dryer, vacuum pump with displacement of at least 163 liters/minute, and freeze dry glassware (if not bulk freeze drying) are required (not included).
