as anyone knows, unsealed concentrate bottles (especially colour
developer and paper B&W developer) rapidly oxidize when broken in. the
solution was to use some CO2 spray made for photographic purposes like
tetenal protectan which is, alas, discontinued.

so I went to a specialist for bottled gas containers in the Industrial
Area of Iraklion...the smallest one they had was 6 liters, the contnet
itself was only 20 euros, but the bottle cost 140 euros!!! too bloody
expensive, and too much gas....so what else? Google it! I found this
little bottle only for 5 euros, plus 7 euros for posting it to me!!!
You may also look into "wine preservation" canisters, which are little
spray cans filled with nitrogen, CO2, argon, etc. basically meant to
displace the oxygen out of your opened wine bottle. I see them on Amazon right now for about $11 USD.

okay thanks but amazon com will not deliver in Greece. such things are considered dangarous to be put into planes; macodirect.de will deliver
RA4 chemicals only with truck or train and it goes from city to city; nurnemberg, budapest, sofia, thessaloniki, athens, iraklio. after a
meticulous google search I found this:α CO2 dispenser that uses CO2 BB
gun ampules which cost 1.2 euros each!!! the dispenser itself costs 18
euros, say 25 euros with post etc. I have a BB gun but without ampules,
the one that you "break" the barrel to load the pellet and build the
pressure necessary to fire it.

this is supposed to be used to test for some bee illnesss, if I got it correctly (it's in greek of course). I couldn't find something similar
in Greece to the wine preservation thing, I don't know even how it would
be called in Greek!!
