Review: These are fantastic great price - Beautiful glaswere for my lab and will be used very soon prober size fit my heating mantel perfectly
Review: 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.
