[3dem] Ethane Cylinder Age

[Thomas, Leonard M.]

Hello All,

Sort of oddish question but how long is a research grade Ethane cylinder good for?  We have one that is probably at least 6 years old and I was wondering when I should worry about the quality of the ethane for plunge freezing.  It really was not used much when it was first purchased but has been since we got a hold of it.

Thank in advance for any thoughts,
Len
