The Labconco FreeZone 12 Liter Console Freeze Dryer is designed for lyophilizing moderate to large sample loads or numerous small container batches. The console features a front viewing window, interior space for a vacuum pump, and accommodation for a full-size tray dryer such as the FreeZone Stoppering Tray Dryer (pump and tray dryer sold separately). Dual 3/4 hp HCFC/CFC-free refrigeration systems cool the upright stainless steel collector coil to -84° C, suitable for low eutectic point samples including acetonitrile.
Product Features
- Upright stainless steel collector coil capable of holding 12L of ice before defrosting; stainless steel collector lid, 3/4" thick, with neoprene gasket
- Console cabinet with interior space for vacuum pump (sold separately) and two-piece, removable front panel with viewing window
- Clear acrylic chamber lid, 3/4" thick, with neoprene gasket
- Brushed stainless steel and glacier white, powder-coated steel exterior with blue accents
- Full color, 5" capacitive touch screen with Lyo-Works OS:
- Real-time display of collector temperature, vacuum level, and optional End-Zone end point detection system
- Start-up mode for collector cool-down and vacuum pull-down (automatic or manual)
- Operating mode (standby or run)
- Vacuum set point, alerts, diagnostic tests, user manual, defrost control, and optional drying accessory parameters
- Data logging stores and displays data in table or chart format; export via USB or Ethernet
- Settings include language, time, time zone, temperature (°C or °F), and vacuum (mBar, Torr, or Pa)
- Alerts programmable to send via Ethernet connection to user-entered email addresses
- Display settings include brightness, touch sounds (on/off), and screen timeout in minutes (on/off)
- Maintenance alert settings include vacuum pump oil change, refrigeration cleaning, total operating hours, and line voltage offset
- Level-specific security lock-out prevents changes to programs and other system parameters
- Hot gas defrost with auto shut off at +60° C
- On/standby switch
- Moisture sensor prevents refrigeration or vacuum start-up when moisture is detected in the drain line
- Vacuum control valve maintains vacuum level set point
- Vacuum break valve bleeds air into the system when power to the freeze dryer or vacuum pump is shut off; if outage less than ~5 minutes occurs, freeze dryer restarts automatically, otherwise manual restart required
- Side-mounted USB port and rear-mounted Ethernet connection
- Front-mounted quick-disconnect drain hose fitting and side-mounted lanyard with hose connector (18", 1/4" ID silicone tubing and clamp included)
