Feeze Dryer

The FreeZone Plus 2.5 Liter Cascade Benchtop Freeze Dry System has a small footprint and reaches -84°C for processing samples with low eutectic points. Its upright stainless steel collector coil can remove 1.8 liters of water in 24 hours and holding 2.5 liters of ice before defrosting is necessary. The FreeZone 2.5 Liter Cascade Benchtop System is suitable for small sample loads or dedicated use by one researcher.
