Review on Borosilicate Glass Graduated Cylinder by Karter Scientific 213I12 by Brandon Woodson

Lately I can't buy 70% or 91% isopropyl alcohol anywhere due to the pandemic. However, I can find pure USP isopropyl alcohol online and use it to dilute to the correct percentage with distilled water. Works perfectly. My only complaint is that it doesn't come with one of those plastic bumpers that go around your neck and keep it from breaking if it tips over. I have a lot of lab experience and am not in the habit of knocking over glassware (if I were such a clumsy teenager I would have put myself into orbit with some of those crazy things!), but it's a nice feature.
