Subject: LN2 for tissue storage
A lab tech asked us this today and I thought that DCHAS-L might know
more than we could find on google:
We recently purchased a LN2 cryo tank for storing tissue samples.
The study requirement is that the tissue samples be stored in the
liquid phase of LN2. So far all the folks that I have spoken to
around here store in the vapor phase - not liquid. I have been
searching online trying to find information on user safety protocols,
PPE, and any other helpful pointers for adding and retrieving samples
from liquid LN2, but not finding as much details as we would like.
Do you know anyone who stores samples in the liquid phase of LN2?
Or, any other suggestions?
Thanks for any information.
