We are passionate about STEM for junior high and high school kids. A lot of what we do is related to making, programming, experimenting, calculating and learning from the results. The goal is to learn from the projects while having fun.
Great seller. Great communication. Item was super delayed with shipping and seller was willing to send another one. He also said to keep the first one. eBay needs more sellers like this.

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.
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.
