FreeZone 6 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 Dryers (pump and tray dryer sold separately). These models offer the broadest range of built-in options including a shell freezer.

The upright stainless steel collector coil holds 6 liters of ice before defrosting. A single 3/4 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 touch screen. Models with PTFE-coated collectors that can withstand corrosive compounds are available.

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

• Upright stainless steel collector coil capable of holding 6L 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 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, 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.

• 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.)

• Built-in shell freezer with stainless steel bath that includes 1/2 hp HCFC/CFC-free refrigeration system capable of cooling the heat transfer solution to -40° C (-40° F), 3/4" thick high-density polyethylene lid, neoprene gasket and front-mounted, quick disconnect drain hose fitting and 18", 1/4" ID silicone tubing with clamp.

• 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.
