FreeZone 4.5 Liter Benchtop Freeze Dryers are ideal for laboratories working with light to moderate sample volumes. Their compact size makes them especially suitable for spaces with limited bench area.
The stainless steel upright collector coil can hold up to 4.5 liters of ice before requiring defrost. A 3/4-inch thick collector lid includes a 3-inch diameter port for connecting drying accessories (sold separately) and is sealed with a neoprene gasket.
- Ice Holding Capacity: 4.5 L
- Collector Temperature: -50 °C / -58 °F
- Collector Coil & Chamber Material: Stainless steel (PTFE-coated models available; contact for pricing)
- Vacuum Pump Requirement: Minimum 98 L/min displacement, 0.007 mBar ultimate pressure, and compatible with 3/4 in. ID vacuum hose
Lyo-Works OS, displayed on a 5-inch full-color capacitive touchscreen, provides real-time readouts of collector temperature, vacuum level, and optional End-Zone end-point detection.
Models are available with PTFE-coated collectors for added resistance to corrosive materials.
