Has anyone used these type of bottles https://www.fotoimpex.com/darkroom/...-wide-neck-brown-1000ml.html?cache=1607221066 to store chemicals?
Except OxygenHDPE bottles are resistant to everything you will encounter in photography
Brown standard-glass bottles with narrow mouth and screw-on PE cap seems the most cheap regular chemicals bottle available here.Hi,
I like glass bottles, but for photographic solutions modern lab screw bottles (Schott Duran GL45 or wide GLS80) are better.
Quite expensive when new, but with some luck you find a bargain on an auction site...
It's what manufacturers use to package chemistry. A well made bottle such as made by Thermo Fisher sold as Nalgene is as good as it gets. Glass is great if you can work safely with it. I worked in labs where I handled concentrated acids daily. We didn't use silly glass stopper bottles. We purchased concentrated Nitric, Hydrochloric and Sulfuric acids in 5 pint Safe-T-Cote bottles. Glass with a thick vinyl coating. If the bottle was broken the plastic coating would contain it for safe disposal.Except Oxygen
Peronally, I like these bottles for my darkroom. Both the bottle and cap are square so are easy to hold and use with wet hands. The only problem is, they come filled with some sort of liquid that needs to be dumped out first. Otherwise, they're great.
Remember the cubitainers that Kodak used for liquid chemistry ? The mylar wine bags are even better.I find it hard to squeeze the air out of glass bottles, so I use bladder bags.
I went down a bit of a rabbit hole looking up Nalgene in response to this interesting post.It's what manufacturers use to package chemistry.

Glass is a pain in the butt. We had a 5 gallon bucket for broken flasks pipets etc.
It does look GREAT! Definitely what would be used on TV!
Yes I was involved in converting all of the polycarbonate parts to Eastman polyester. The BPA concern crushed the use of polycarbonate in food contact use. No clear evidence was shown that polycarbonate caused problems, but consumers made the choice.I went down a bit of a rabbit hole looking up Nalgene in response to this interesting post.
It appears that Nalgene can refer to a variety of materials. And that the HDPE versions of Nalgene aren't necessarily the same as other HDPE examples. And that Nalgene has limited resistance to strong oxidizing agents.
All of which is to say that it is difficult to point to a single material and say definitively that it works - the quality and application of that materials matters.
Interestingly enough, it appears that Eastman Chemical are the source for the Tritan used in many Nalgene bottles.
I fully agree that one feels safer with strong acids in unbreakable (HDPE or other) bottles. Strong acids are not altered by atmospheric Oxygen. OTOH, photo developers are degraded by Oxygen. My point was that there are polymers with better barrier properties than HDPE, e.g. PET or PVA.We didn't use silly glass stopper bottles.

A lot of the bears in the far North of Canada and in Alaska are also called Kodak as well, aren't theyI'm afraid though that my favourite pharmacist assistant there might not get along well with the OP - she has a dog named Kodak!
