ABSTRACT:
A cryogenic extractor having a self-contained filler, and a tip activated by slanting the tip down. A cryogenic extractor has a foward chamber having a rod to be cooled, the rod extending adjacent to the top wall so the liquid will not reach the rod when the extractor is held horizontally with the bottom down. The extractor has a rear chamber for receiving the liquid refrigerant on filling. A filling cartridge is received in the rear chamber, and a base holds the cartridge. The base receives the skirt of the rear chamber on one step for shipping, and on another, lower step for use. The skirt must be forced over the lower step, and the fit holds the skirt in place and, provides a tight seal. An activator on the cartridge is pushed down when the extractor is pushed down, dispensing the refrigerant from the cartridge, and the refrigerant flows down into the rear chamber. The extractor can be tipped to a horizontal position and rested on the bottom without activating the tip, and further slanting of the extractor will cause the liquid to engage the metal rod to activate the tip.
