Used Lab Equipment

The FreeZone Triad Freeze Dry Systems 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.
