Thick glass, durable but doesn’t fit keck clips
First arrived damaged but seller replaced immediately. Delivered in a bulging polystyrene box so no surprises why the first got smashed. The glass is pretty thick so I’m not worried about accidentally smashing it on something, but thermal gradients may be an issue. The ground joint is also very thick glass and is too big for keck clips, they should really provide a special clip with the flask if it’s going to be that chunky. Joint fits other glassware well.

Heavy wall recieving flask works great under high vacuum. Ground glass fitting was a perfect match to my male end and had no vacuum leak with apiezon high temp vac grease on the fitting. Distillation ran smoothly
