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 (-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.
Features
- 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.
- 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.
- Hot gas defrost with auto shut off at +65° C (+149° 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.
- 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-wire electrical cord with plug.
- 3/4″ OD vacuum connection, 50″ of 3/4″ ID vacuum hose and two clamps.
Options Include
- PTFE-coated collector coil and chamber for processing involving corrosive compounds.
- 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.
- Small Tray Dryer or other drying accessory.
- Freeze dry glassware if not bulk freeze drying.
