Review: No surprises, does the job. - Well-packaged for shipment, well-made; does the job. Will pop open if subjected to positive air-pressure and can wedge closed if large negative pressure is applied. The inner and outer portions are mated with a conical fitting, frosted glass. Fits well, but not with a large pressure differential between inside and outside.
Review: Awesome, thick glass! - It served me well until it slipped from my hands and crashed on the concrete floor from 3 feet. So I was able to confirm that the glass is 2mm thick. Well made and I am getting another for replacement...

### ⭐⭐⭐⭐⭐ Great Product!!!!
*by R***S on August 11, 2024*

If you want to use as cold trap. Put 3 or 4 inline!!! Perfecto!!!!!! Stops everything!!! For Buchner filtering it saves you from ruining your pump. Those of you with food freeze dryers could easily have a setup and keep their oil clean from water and smells. You would need to match the connections. This company is really good!
