It may work to put nitrogen in from welding supplies just an idea put in ballon first then slowly flood open coating bottle to displace normal air ... or helium

Get your point...I could also purchase a cannery and utilize their vacuum machines as well

Good idea on nitrogen overlay

I buy my coating bottle at glass bottle bottle outlet I don’t use euro dropper I use pressure cone style fill up to bottom of neck the pressure cone style is air tight I buy coating in liter option from Japan and transfer to 30 ml.

Another great idea by Mgavin. The less headspace (where air accumulates) the better

Is this what you mean by a "pressure cone" style bottle cap?

Yes so you fill up to slightly above bottom of bottle where liquid starts going into neck that leave little air left. When you screw the top on it compresses that little bit of air. When screwing cap down there should be resistant that how you know you have enough liquid in there. If there is no resistance you need to put more liquid in. When there is enough liquid and the compression of the air push back you get an amazing seal you have the cap screwing on the outside of the bottle and you have cone seated by the pressure on the inside of the bottle.

mgavin...I can't thank you enough for your experience on this.

Here I am worrying about 50ml of liqud, and your going through this 1 liter at a time!

Curious...do you keep the liter amounts refrigerated when not in use? Or should that not matter, providing the seal on the bottle is air tight?

Air is your enemy {oxygen cause oxidation and degrades things, how ironic). I work on oncology drugs and I overlay the active compound with nitrogen ( in a vial, with the least amount of headspace)
Same goes for coatings in containers, the less air the better
