Preserving shake?

Is there a way to preserve shake for a later time? Like 2 weeks or so?

Just keep it in a cool dark place. I will keep for quite a while that way alone.

Vacuum seal in titanium capsules and store in liquid nitrogen vats protected by Faraday cages, all 30 feet or more below the ground. Don't take any shortcuts!

This is the only thread I've been able to find on nitrogen during storage process. Any recommendations on nitro vacuum sealers?
