The chamber pre-freezes samples on the shelves eliminating the need for a separate freezer and product transfer. The collector reaches -85ºC and has a 2.5L ice holding capacity. The Tray Dryer has a built-in pneumatic stoppering mechanism that stoppers vials under vacuum. Compressed gas is not required. One temperature probe monitors product temperature. The shelf temperature ranges from -75ºC in pre-freeze mode to +50ºC for secondary drying. A 1/8" OD backfill port introduces sterile air or inert gas before vials are stoppered thereby protecting samples from atmospheric moisture and contaminants.

Two ½ CFC-free and HCFC-free refrigeration systems are used in series to cool the collector to -85º C (-121º F), ideal for samples with low eutectic points. They work in concert with a 1000-watt 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.
