StonyLab Borosilicate Glassware

Can anyone speak to the durability or quality of Stony Lab’s separatory funnels?

Welcome to the Future!

I have seen some use their glassware and it was decent. No serious issues but not top quality either

2¢,
Cheers!

I broke a 250mL flask this week by warming ethanol to boiling point while stirring😅
