Thought this was supposed to fit my Erlenmeyer flask but was a little too big. Not Northern brewers fault or product defect. Just didn’t fit right. Oh well, didn’t cost much
It fits, but not too snugly. I have to keep pressure on the top to prevent it from popping off
Perfect for my 2 Liter flask to grow and proof my yeast.
Yeah, thought this would fit in my 2L erlenmeyer and glad it did. Walter White would be proud.
