I need to send something like 80 eppendorf tubes (1,5 ml volume) in liquid nitrogen, but it's apparently quite complicated. Could someone suggest me a good company to do that?
Thank you very much, my only worry is the uncertain time of delivery of my RNA samples, the time they could be stopped in airports, and so on, and I was told that in Liquid nitrogen they are safe for a longer time (even 10 days, is that possible?).
