The FreeZone 4.5 Liter Benchtop Freeze Dry System is a compact laboratory lyophilizer with ice holding capacity for light to moderate sample loads. It has a permanently installed 10-port drying chamber and a compact benchtop design. A vacuum pump and sample containers, such as flasks, are the only additional components necessary for a complete system.
Its upright stainless steel collector coil can remove over 2 liters of water in 24 hours and hold 4.5 liters of ice before defrosting. A 1/3 hp CFC-free refrigeration system cools collector to -50°C (-58°F).
LCD displays system operating parameters, set up parameters and alarm messages. It is user-configurable to display vacuum in mBar, Pa or Torr and temperature in °F or °C. It also displays total number of hours of refrigeration operation and since the refrigeration was serviced and the total number of hours of vacuum pump operation and since the vacuum pump was serviced.
Red alarm light flashes and beeper sounds to indicate an abnormal system event has occurred, including: power failure, improper line voltage supply, collector temperature rise above -40°C, service vacuum pump (after 1000 hours of vacuum use), and moisture in collector. Pressing the Menu Switch displays the alarm message on the LCD.
Moisture sensor prevents refrigeration or vacuum start up when moisture is detected in the collector chamber area. Optional Teflon®-coated collector chamber and coil is for processes involving corrosive compounds. Domestic or international electrical configurations are available.
Required accessories include rotary vane direct drive vacuum pumps with a displacement of at least 86 lpm, 0.002 mBar ultimate pressure and a fitting suitable for 3/4” id vacuum hose as well as freeze dry glassware.
