I am working on some field based experiments looking at metabolomics in Tilia. This experiment requires the use of liquid nitrogen which we can take to the different sites we are working on. Does anybody have any 3 Litre (ish) dry shippers that we could borrow for a few days in August 2015? I would be really greatful if anybody could help, we do not have a big budget for the project and dry shippers can be a bit pricey.

We are based in the North West of England.
