I run the chemistry laboratory program at a large community college. The longer I do the job, the more I use plastic bottles. But I wouldn’t store con. sulfuric in any kind of polyethylene or polypropylene. Even if they work over a period of weeks, over long term the plastic will get brittle. I use teflon for con. sulfuric, nitric, and hydrochloric, but at $30 ea for a 125 mL bottle, it’s too much for kits. Go with glass. Azap
