The Labconco FreeZone 4.5 Liter Benchtop Freeze Dryer is designed for lyophilizing light to moderate sample loads, featuring a compact benchtop design perfect for labs with limited space. With a PTFE-coated collector coil that withstands corrosive compounds and advanced refrigeration reaching -105° C, it is ideal for processing low eutectic point samples such as acetonitrile and dilute methanol or ethanol. The Lyo-Works OS displayed on a 5" full color capacitive touch screen ensures intuitive and real-time control of all critical parameters.
Product Features
- Upright stainless steel collector coil holds 4.5L of ice before defrosting
- Stainless steel collector lid, 3/4" thick, with neoprene gasket and 3" diameter port for drying accessories (sold separately)
- PTFE-coated collector to handle corrosive compounds
- Compact benchtop design with small footprint
- 5" capacitive touch screen with Lyo-Works OS: real time display of collector temperature, vacuum level, and optional End-Zone end point detection
- Start-up mode for collector cool-down and vacuum pull-down (automatic or manual)
- Operating modes: standby or run
- Vacuum set point, alerts, diagnostic tests, user manual, defrost control, and optional drying accessory parameters
- Data logging in table or chart format, exportable via USB or Ethernet
- Settings: multi-language support, time, time zone, temperature units (°C/°F), vacuum units (mBar, Torr, Pa)
- Programmable alerts via Ethernet to user-specified email addresses
- Display settings: brightness, touch sounds on/off, screen timeout
- Maintenance alerts: vacuum pump oil change, refrigeration cleaning, total hours, and line voltage offset
- Level-specific security lock-out
- Hot gas defrost with auto shut off at +60° C
- On/standby switch
- Moisture sensor prevents refrigeration or vacuum start-up if moisture is detected in the drain line
- Vacuum control valve maintains set vacuum level
- Vacuum break valve protects system during power loss; if outage is under ~5 minutes, system restarts; if longer and collector warms above safe limit, system does not restart automatically
