The Labconco Freezone Plus 6 Benchtop Freeze Dryer is specially designed for samples with low eutectic points. Freeze drying is especially suited for substances that are heat sensitive, making this laboratory freeze dryer ideal for not only food processing, but also in the development of pharmaceuticals, and in the preservation of biological samples. The Labconco Freezone Plus 6 Benchtop Freeze Dryer is constructed of an epoxy coated steel exterior, upright stainless steel 10 Port T-Style Manifold and coil, with ½” thick clear acrylic lid and neoprene gasket. This lyophilizer can remove up to 4.1 liters of water over 24 hours, holding 6 liters of ice before defrosting, and performs best when the ambient room temperature is 70° F (21°C) or cooler. The refrigeration system on this lyophilizer is a dual 1/3 hp CFC free refrigeration system, with collection temperatures at  -84° C, -119° F. A LED “wave” display provides users with an at a glance status update while operating. This 6 liter cascade freeze dryer also features a purge valve and built in drying chamber. 


At the rear of the Labconco Freezone Plus 6 Benchtop Freeze Dryer users will find a RS-232 port for transmitting data to a PC, which can be configured at intervals of 30, 60, 300 or 600 seconds. Also on the back of this benchtop freeze dryer, users will find manual overrides for the vacuum and collector, as well as automatic start up switches. On the front of the Labconco Freezone Plus 6 Benchtop Freeze Dryer parameters and alarm messages are clearly displayed on a LCD screen. Users can select display choices for temperature (°C or °F) and vacuum (mBar, Pa and Torr), as well as the total number of hours of refrigeration and vacuum system operations, and time elapsed since either system was last serviced allowing users to stay on top of maintenance.
