Benchtop Stoppering Tray Dryer and Lyophilizer
Booth 4147. The FreeZone Triad benchtop stoppering tray dryer and lyophilizer incorporates four valves to allow lyophilization in flasks simultaneously with samples in the tray dryer. The chamber pre-freezes samples on the shelves, eliminating the need for a separate freezer and product transfer. The collector reaches -85 C and has a 2.5-L ice holding capacity. The tray dryer’s built-in pneumatic stoppering mechanism stoppers vials under vacuum. Compressed gas is no longer required, and one probe monitors product temperature. The shelf temperature ranges from -75 C in pre-freeze mode to 50 C for secondary drying. In addition, a 1/8 OD backfill port introduces sterile air or inert gas before vials are stoppered. Two 1/2 CFC-free and HCFC-free refrigeration systems are used in series to cool the collector to -85 C, which is suited for samples with low eutectic points. They work in concert with a 1000-W heater to cool and heat fluid medium circulating through channels in the shelf. A rear-mounted RS-232 port transmits data to a user-supplied computer. Transmission intervals may be user-configured for 10, 20, 60, 300 or 600 minutes.
