Labconco FreeZone 4.5L -84C Benchtop Freeze Dryer with PTFE coil and collector

• Patented moisture sensor protects the vacuum pump by preventing refrigeration or vacuum start-up when moisture is detected in collector chamber area.
• Vacuum control valve maintains set point vacuum level to speed the freeze drying process.
• Lyo-Works OS provides a real time display of collector temperature and vacuum level
• Flexible programming and control of optional drying accessories
• Optional End-Zone™ end point detection for flask freeze drying
• One-touch data logging and display provides information to maximize sample quality and minimize run time
• FreeZone exclusive features protect your vacuum pump from costly damage: A vacuum break valve bleeds air into the system when power to the freeze dryer or vacuum pump is shut off for more than 5 minutes. A moisture sensor prevents refrigeration or vacuum start-up when moisture is detected in the drain line. Vacuum pump is automatically shut down when a leak is present in initial pull down or during run

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.

A variety of FreeZone Freeze Dryer accessories are available including Shell Freezers, Tray Dryers, Drying Chambers and Product Shelves.

Memory to store 30 programs with 16 segments each including number of steps, ramp rate, shelf temperature, hold time and vacuum level

FreeZone 4.5 Liter Benchtop Freeze Dryers are designed for lyophilizing light to moderate sample loads. The compact design is ideal for labs with limited floor space. The upright stainless steel collector coil holds 4.5 liters of ice before defrosting. Two 1/3 hp HCFC/CFC-free refrigeration systems cool the collector to -84C (-119F), suitable for low eutectic point samples including acetonitrile. 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.
