When it comes to vacuum filtration, a heavy-duty flask is a must and this item meets all specifications.

Nice piece but the lip of the neck has an irregularity that makes sealing awkward at times. Other than that, its everything I always wanted in a 50-0 filter flask.

It a solid device glass that I can place Potassium hydroxide into with a rubber stopper No.6 and neutralize harmful gases from certain projects like making Aqua regas. Glad I ordered it.
