So i just came across these diamond miners online and had a few questions about them if anyone can help. Firstly i'd like to know if these are a safe option for storing your butane solution in the freezer overnight for winterization? Also, if i wanted to use Nitrogen assist to add pressure to one of these would a small Nitrogen cartridge suffice? As these look rated upto 60psi and i'm sure the diamond miner needs about 10psi? I'd appreciate any help. Thanks
