Try contacting Dave Morgan at Minox who purge their bins with argon gas - he's very helpful.
It's dave(AT)minoxuk.co.uk or log on to the Minox site at Birdforum and pose the question there - you're bound to get lots of info!!
Cheers

As to gas, I prefer Helium to either Argon or Nitrogen... makes even a 15x56 a joy to carry. :loveme:
engineer said:Nitrogen has an atomic number of 7, whereas argon has an atomic number of 18. Hence, argon is larger as John said. Larger molecules don't leak as easily as do smaller molecules.Ah but, argon is a monatomic gas (i.e. consists of single atoms) and nitrogen is a diatomic gas (molecules contain two atoms), which would make nitrogen molecules physically much bigger. An argon atom has a relative mass of 40, a nitrogen molecule has a relative mass of 28. I suspect that he difference in mass is far less significant than the difference in physical size, as far as leaking out is concerned.
In reality, it matters not a jot, but I am an ex science teacher, and old habits die hard....
