Title: Bottles for storage of liquid standards
Post by: pcm81 on May 31, 2019, 12:53:06 PM

Looking for suggestions on bottles or jars for storage of titration standards like acids, dilute bases (NaOH, KOH etc) and oxdizers/reducers (KMnO4 etc).
I am thinking something like this from Amazon:
Qorpak 239215 ValuLine Amber Glass Wide Mouth Packer Bottle with Polypropylene F217 and PTFE Lined Cap, 32oz Capacity, 99mm OD x 178mm Height (Case of 12)

Are there better choices? My main concern is contamination of the solutions by reaction with cap or cap liner, while also actually having a screw on cap to be spill proof.
Some acids will be gaseous type... HCl but at low concentrations.

Thanks

It should be fine, my main concern for you would be to store the KMnO₄ separate from the acids and bases. Same goes for the acids and bases. Don't keep them together, find separate secondary and tertiary containment.
