Not sure where to post this. Swim is preparing reagent-grade HCl using this method, and is wondering what containers can safely hold ~16% (~5.1 Molar) HCl. He doesn't know if he can acquire a glass bottle w/ an airtight glass stopper. Would an HDPE container with a PP or LDPE top work, or could that be corroded?

HDPE can handle HCL just fine at higher concentrations than what you're dealing with. Have funVery happy

Only problem is that SWIM has been unable to find any HDPE containers that don't have PP or LDPE caps. Do you know if it'd be OK to have the bottlecap be made of one of these materials?

Sorry it took me so long to respond. LDPE is completely resistant to average concentrations of HCL as far as I know too. 99% sure
