The Labconco FreeZone 4.5 Liter Benchtop Freeze Dryer is engineered for lyophilizing light to moderate sample loads, combining a compact footprint with advanced features for modern labs. It features an upright stainless steel collector coil holding 4.5 liters of ice before defrosting and a robust refrigeration system cooling to -50° C, suitable for aqueous samples. The intuitive Lyo-Works OS, displayed on a 5" full-color capacitive touch screen, provides real-time monitoring of collector temperature, vacuum level, and optional End-Zone detection, making freeze drying processes easier and more reliable.
