Pope Scientific Glass Gas Marinelli

Pope Scientific Glass Gas Marinelli
An interesting piece of laboratory glassware that tech services at work were going to throw out many years ago.
I used this a few times but we switched to plastic gas marinellis since these were very expensive to replace when broken.
I'm certain that there haven't been glass gas marinellis made for many years now.
I asked him if I could have it .... saving it from the trash.
Kinda' cool looking and very unique.
Soda can is in the last pic for a size comparison.

Thanks Much for looking at my Pope Gas Marinelli!
