Designed for light use, the compact Labconco 4.5 Plus Freezone Benchtop Freeze Dryer handles samples with low eutentic points, as well as samples containing acetonitrile. This lyophilizer can remove up to 4 liters of water over 24 hours, holding 4.5 liters of ice before defrosting, and performs best when the ambient room temperature is 70° F (21°C) or cooler. Dual 1/3 hp HCFC/CFC free refrigeration systems bring the temperatures as low as -84° C (-119° F).

The Labconco 4.5 Plus Freezone Benchtop Freeze Dryer is constructed of an upright 12 port stainless steel collector chamber and coil, with a brushed stainless and powder coated steel exterior.  Freeze drying is especially suited for substances that are heat sensitive, making it ideal for food processing, but also in the development of pharmaceuticals, and in the preservation of biological samples.

Parameters and alarm messages on the Labconco 4.5 Plus Freezone Benchtop Freeze Dryer are displayed on a LCD screen showing users choices in temperature, vacuum display (vacuum in mBar, Pa and Torr). Clearly displayed on the front of the machine also displays the total number of hours of refrigeration and vacuum system operations, as well as time elapsed since either system was last serviced allowing users to stay on top of maintenance. A LED “wave” display provides users with an at a glance status update while operating. Alarms on this lyophilizer are both audio and visual to alert users to abnormal system events such as power failure, improper power supply, change in temperature, moisture in the collector, and vacuum service.

At the rear of the Labconco 4.5 Plus Freezone 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 are manual overrides for the vacuum and collector, as well as automatic start up switches.

*not for use with samples containing methanol or ethanol.
