Description
The Worthington Industries Extended Time (XT) Series of cryogenic refrigerators is designed for extra-long term storage of biological material at liquid nitrogen temperature. Seven different models provide alternatives between portability, sample storage capacity and holding time to fit a variety of storage needs.
LN2 applications range from industrial to laboratory, biological and non-biological material. Low profile (XTL) models are available for applications where a shorter unit is needed.
Optional accessories include low level alarms for passive monitoring of liquid level, roller bases for ease of movement, and measuring rods for determining liquid levels inside the refrigerator.
Product formerly branded CryoScience by Taylor-Wharton, which was acquired by Worthington Industries.

(1) Evaporation rate and static holding time are nominal. Actual rate may be affected by the nature of the contents, atmospheric conditions, container history, and manufacturing tolerances.(2) Working Time is an arbitrary, reference-only value to estimate container performance under the actual operating conditions.(3) Without canisters.(4) Canisters also available in 5.0 in. (127 mm) height for 10XT, 20XT and 34XT.
