FreeZone 12L -50° C Console Freeze Dryer

FreeZone 12 Liter Console Freeze Dryers are 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 large tray dryer such as the FreeZone Stoppering Tray Dryer (pump and tray dryer sold separately).

The upright stainless steel collector coil holds 12 liters of ice before defrosting. A single 1 hp HCFC/CFC-free refrigeration system cools the collector to -50° C (-58° F), suitable for aqueous samples.

Lyo-Works™ OS provides a real time display of collector temperature, vacuum level and optional End-Zone™ end point detection system, shown on a 5″ full color, capacitive touchscreen. Models with PTFE-coated collectors that can withstand corrosive compounds are available. Built-in options include a purge valve and mini chamber.

Vacuum pump, drying accessory and freeze dry glassware (if not bulk freeze drying) are required (not included).

Features (All Models)

• Upright stainless steel collector coil capable of holding 12L of ice before defrosting. Acrylic collector lid, 3/4″ thick, has 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 touchscreen 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, and may be exported via USB or Ethernet.
  • Settings include language (English, Spanish, French, German, or Italian), time, time zone, temperature (° C or ° F), and vacuum (mBar, Torr, or Pa).
  • Alerts are programmable to send via Ethernet connection to user-entered email addresses.
  • Display settings include brightness, touch sounds (on/off), and screen time out 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 (+140° F).
• On/standby switch.
• Moisture sensor that prevents refrigeration or vacuum start-up when moisture is detected in the drain line.
• Vacuum control valve that maintains vacuum level set point.
• Vacuum break valve that bleeds air into the system when power to the freeze dryer or vacuum pump is shut off. If a power outage less than approximately 5 minutes occurs, the freeze dryer will restart and the refrigeration and vacuum system will resume operation once power is restored. If the power failure is more than approximately 5 minutes and the collector warms above safe limits, the freeze dryer will not automatically restart.
• 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.
• Internal electrical receptacle for vacuum pump connection.
• 3-wire electrical cord with plug.
• 3/4″ OD vacuum connection, 36″ of 3/4″ ID vacuum hose and two clamps.

Options Include

• PTFE-coated collector coil and chamber for processing involving corrosive compounds.
• Purge valve for isolating the vacuum pump from the freeze dryer.
• Built-in stainless steel mini vacuum drying chamber that includes 50-watt heater with microprocessor control to +60° C (+140° F), 3/4″ thick clear acrylic lid and neoprene gasket. (Chamber is not cooled.)
• Region-specific electrical plug configurations.

Required Accessories (Not Included)

• Vacuum pump with a displacement of at least 98 L/min, 0.002 mBar ultimate pressure and fitting suitable for 3/4″ ID vacuum hose.
• Tray dryer or other drying accessory.
• Freeze dry glassware if not bulk freeze drying.
