Great flask
These are very heavy walled flasks and can clearly handle the vacuum.

HIghly efficient condenser
If you are distilling with high power you need large surface area in the condenser. The advantage of this design is the double wall construction. It improves efficiency in a compact design.

Great Price and Poor Quality
I use a lot of 2000ml round bottom flasks and have purchased all major brands.
Half of the flasks I ordered had small defects that looked like bubbles close to the surface of the glass that had opened up. I use flasks for vacuum distillation, so could not use the defective ones to guard against implosion.
The price is great and if your application does not need vacuum these might just be the thing you need.
