The FreeZone Triad Freeze Dryers offer it all for lyophilization: stoppering tray dryer and sample freeze drying with four sample valves on the left side. Samples for both types of freeze drying can be run at once. The chamber pre-freezes samples to save money and time, eliminating the need for a separate freezer and product transfer. User-friendly controls enable you to start runs quickly and the microprocessor controls up to five different ramping and holding segments to meet different temperature protocols. The hot gas defrost allows for easy cleanup of up to 1.8 liters of water or 2.5 liters of ice. The built-in pneumatic stoppering mechanism doesn't require compressed gas and can handle glassware from 31mm to 148mm on its 12.4"w x 14.5"d shelf. Two 1/3 hp CFC-free and HCFC-free refrigeration systems cool the collector to -85C (-121F) to process low eutectic point samples including ones containing acetonitrile.
- Stainless steel collector coil capable of removing 1.84 L of water in 24 hours and holding 2.5 L of ice before defrosting
- Two 1/3 hp HCFC/CFC-free refrigeration compressors cool the collector to -84° C (-121° F) and work in concert with a 1000-watt heater to cool and heat fluid medium circulating through channels in the shelf. Not for use with samples containing methanol or ethanol
- Processing shelf, 12.4" w x 14.5" d (31.5 x 36.8 cm). Spacing between shelf and top of chamber accommodates containers with stoppers up to 148 mm maximum height
- One probe for monitoring temperature of sample in chamber
- Temperature ramp and hold programming from -55° C to +50° C (-67° F to +122° F) and -75° C (-103° F) during pre-freezing. Controls temperature to ±1° C of set point. Memory to store 30 programs with 16 segments each including number of steps, ramp rate, shelf temperature, hold time and vacuum level
