Professional Glass Quality A+++
Excellent packaging, Quality thick glass, for professionnel lab, high heat resistant since its for hot filtration during recrystallization. A+++ I recommend it. (Remember to buy a rubber seal to get good suction during vacuum for best results)

Does what i's supposed to.
Does what it's designed for but I got the feeling the tubing attached could have come off easier. I think this is due to the grooves on the connector being a little sharp. 4* out of 5* for a good product.

Well packaged.
Nice piece at a Good price. VERY well packaged. Amazon proof packing. Well done. NOTE: This did fail on me. Imploded and covered me in acid. Not sure why it failed. Please use caution in the lab. PPE always.
