EISCOErlenmeyer Flask, 5000ml - Borosilicate Glass - Narrow Neck, Conical Shape - White Graduations

What can I say? It's a big-ass, sturdy flask. Good luck finding a magnetic stirrer under $200 that can vortex 5L of anything, though.

Don’t spend the extra money for a heavy duty piece of glass, this is not it. Lighter especially in the neck and rim than the 4 liter flask I had and broke.

The glass split in two pieces when it was full of liquid what a horrible mess.

Great flask

This product works ok, but the temper allowed for a color change despite minimal heat
