6L Freeze Dryer w/Stoppering Tray Dryer with purge valve
FreeZone 12 Liter Console Freeze Dry System is designed for moderate aqueous sample loads. This model is not for use with samples containing acetonitrile. Removes a maximum of 8 liters of water in 24 hours.
FreeZone Plus 6 Liter Cascade Console Freeze Dry System is designed for light to moderate loads of low eutectic point samples. Removes a maximum of 4.1 liters of water in 24 hours.* Includes brushed stainless steel and powder-coated steel exterior; stainless steel collector chamber and coil; LCD that displays system operating parameters, set-up parameters and alarm messages (choice of temperature in °C and ° F, choice of vacuum in mBar, Pa and Torr); two 1/3 hp CFC-free refrigeration systems; red alarm light; LED vacuum and temperature wave graphs; patented moisture sensor; vacuum control/break valve; rear-mounted RS-232 port; automatic start-up switch for collector cool-down and vacuum pull-down with manual override switches; hot gas defrost and switch; retractable collector drain line; 3" diameter port for connection of drying accessory; power switch; rear-mounted electrical receptacle for vacuum pump connection (pump not included); 3/4" OD vacuum connection; 3/4" ID vacuum hose; and two clamps.
Lyophilize and stopper multiple vials under vacuum using the FreeZone Stoppering Tray Dryer, or freeze-dry batch samples for bulk processing directly on its three shelves. A digital display allows the user to program the set point temperature. Holds up to five programs of up to five segments each, with memory for repeating protocols.
Stoppering Shelf Details
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.

The Virtis 25EL Freezemobile is a state-of-the-art large capacity Lyophilizer, also known as a Freeze-Dryer, which is a dehydration process typically used to preserve a perishable material (sample), or make the material more convenient for transport. Lyophilization (Freeze-drying) works by freezing the sample and then reducing surrounding pressure to all the frozen water in the sample to sublimate directly for the solid phase to the gas phase.
Includes one 110V manually controlled spare vacuum pump and Computer w/ Hercules 3.2.6 for data collection.
One compressor system, 25 liter capacity with external condenser, three shelves, 4 product sensors, no stoppering system, 220V one phase, 220V one automatic control vacuum pump 5 -10mTorr, data acquisition system, inert gas backfill with proportional valve.
