500ml Borosilicate Glass Vacuum Filtration Flask - Heavy Wall Design with -0.06MPa Pressure for Lab Experiments, Chemistry Filtration, and Scientific Research

This has a nice heavy neck which I need for high volume work. The glassware seems to be true to form in thickness. I’m a very technical person so for the value this would be likely well over a 700+ dollar flask. I’ll revise my review after I’ve used it a few times. For the money I believe it’s a really nice filtering flask.
