QWORK 1000ML Buchner Funnel Kit Filter Flask Set, 1L Vacuum Flask 80mm Funnel, Borosilicate Glass Heavy Wall Filtering Flask

Perfect lab glass, easy to use and clean size is great for the price and comes with a variety of gaskets for getting the perfect seal, also the glass used is super durable and ive dropped a few time, not even a crack!

great setup for a small funnel. No problems. iv'e used it at least 20 times

solid glass ,heavy well made

Over all worth what I paid for it.. just wanted to filter some liquid faster than gravity does.

Thick glass design. Will order again

Poor packaging, funnel and flask were in one layer of small bubble wrap with no other protection. Outer box was in perfect shape but the product box itself was crushed on one edge. Amazingly, it all showed up in one piece. The rubber stoppers came stacked and stuck together. It took me about 30 minutes to get them separated without damaging them too much. They came out MOSTLY unscathed, but it was a heck of a chore getting them separated. The vacuum barb on the flask is quite large compared to all other pieces that I have that take a vacuum, so I will now need to get a new vacuum tube. The flask is quite thick, so I feel like it should be pretty sturdy. The filter housing is thick, with large holes so it won’t clog easily. This isn’t professional quality by any stretch of the imagination. But for the cost, it will get you by until you can get something better.

Perfect for my needs.

Good quality. No issues.

La verdad esq lo único q me daba miedo es que la gente decía que llegaba roto pero el mío llegó en perfectas condiciones. Los de silicona están en buen estado. El embudo buchner tiene solo unos detallitos, está bien, pero en la parte superior hace falta como recubrimiento en en la circunferencia más externa de hasta arriba es un poco complicado explicarlo pero fuera de eso por el precio creo q están pasables porque a diferencia de otro artículos salen al triple de lo que estos cuentan. En cuanto al matraz quitazato lo único es que por dentro tiene como un detallito (como una fisura superficial) solo espero que no afecte en nada cuando esté funcionando.

No visible manufacturing defects I can see. Haven't put a vacuum to it yet but looks like it will be fine. Reasonable thickness of material. I'm pleased. Put this under vacuum today and it works perfectly. No defects. A nice product.

Great for the price, works just like the expensive ones.

El embudo pues... No tanto, llegó roto 💔😞 a pesar de la trajedia del embudo, no hubo ningún problema con el reembolso ni con el reenvío, así que lo compré de nuevo.

Excellent product, works great
