Huaou 250ml Lab Glass Gas Washing Bottle Muencks

Although I knew it had short tube connections, the price is great so I tried it out. With the bottle well clamped, the hose didn't fall off unless I had some moderate bumping going on. I also incorporated a 250mL bump trap, - this was in an effort to increase the volume to reduce pressure build on the wash bottle. Still had some trouble several times.
