FreeZone Triad Benchtop Freeze Dryers are designed for multiple types of lyophilization: flask, bulk and stoppering vials. With the ability to freeze dry samples in so many different forms, the Triad’s versatility and compact design make it perfect for busy labs.
The upright stainless steel collector coil holds 2.5 liters of ice before defrosting. Two 1/3 hp HCFC/CFC-free refrigeration compressors cool the collector to -85° C (-121° F), suitable for aqueous or dilute acetonitrile samples. Temperature-controlled shelves range from -55° C to +50° C (-67° F to +122° F) and a maximum of -75° C (-103° F) during pre-freezing. The shelves provide pneumatic stoppering with a diaphragm, eliminating the need for compressed gas.
Lyo-Works™ OS provides a real time display of collector temperature and vacuum level, shown on a 5″ full color, capacitive touchscreen. A stoppering tray dryer and four valve ports are built-in.
Vacuum pump and freeze dry glassware (if not bulk freeze drying) are required (not included).
Features (All Models)
- 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 -85° 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
