Includes the TGA 8000 Sub-ambient Cooling Tube (N5370333), Hose clamps (09903004) and tubing (02506518) for connecting the Cooling Tube to the Chiller, and Instructions. When combined with the Chiller Accessory (N5370220 for 120V operation or N5370221 for 220 Volt operation) provides the ability to operate the TGA 8000 from sub ambient to elevated temperatures. Additionally allows faster furnace cool down from elevated temperatures at the completion of an experiment. Note: Requires, but does not include a chiller (N5370220 or N5370221).
