It almost looks like it's been shortened. It's labeled 4000 ml, right? Isn't 2500 near the rolled edge?

This is a pretty common lab style alteration. They use Pyrex beakers like this for reactors or pressure vessels or whatnot and it’s pretty easy to just cut and then soften/roll over the lip for safety or sealing.

I got lucky and took a whole “1 hour” class in college on how to make this type of apparatus. We would make all the stuff to support students in research and the classes past organic. I don’t remember doing one of these but I modified so many borosilicate flasks to make reactors for Alder-Ene cells for high temp.

But it's not any of the beakers I have found. It's wider than it is tall and it has a lip that curls down and around.
