FreeZone 8 Liter Benchtop Freeze Dryers are designed for lyophilizing moderate sample loads. The compact design is ideal for labs with limited floor space.

The upright stainless steel collector coil holds 8 liters of ice before defrosting. A single 3/4 hp HCFC/CFC-free refrigeration system cools the collector to -50° C, 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 8L of ice before defrosting. Acrylic collector lid, 3/4" thick, has neoprene gasket and 3" diameter port for connection of drying accessories (sold separately).
• Compact benchtop design with a small footprint.
• 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.
  • 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 +65° C.
• 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.
• Side-mounted, quick-disconnect drain hose fitting and lanyard with hose connector. 18", 1/4" ID silicone tubing and clamp included.
• Rear-mounted electrical receptacle for vacuum pump connection.
• 3/4" OD vacuum connection, 50" of 3/4" ID vacuum hose and two clamps.

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.

- Small Tray Dryer or other drying accessory.

- Freeze dry glassware if not bulk freeze drying.
