Regarding the liquid nitrogen container you had to hire,i have only recently been told of a much cheaper alternative which serves the same purpose,but is disposable & one way. So basically you buy the container & it is sufficient to keep the frozen at the right temperature for four or so days,giving ample time to reach the freezing bank.
Haven't looked further on this,but I would appreciate any input if anyone knows of or has used one.
Sounds very similar to the type which Jack mentions in his DVD,regarding using semen extender in fresh sperm.
Apologies for straying LK. If I get a short reply,then I will open a new thread
