Abstract
A portable refrigerating unit has a condenser coil which may be inserted directly into the drying chamber of a freeze drying apparatus. A flexible tube is utilized to convey refrigerant to and from the condenser coil. The flexible tube and the condenser coil are connected through a closure member, which provides a vacuum tight seal for the drying chamber of the freeze drying apparatus. The closure member may be removed from the condenser coil, so that various closure sizes may be utilized and so that the condenser coil may be utilized as an immersible refrigerating device.
