Trotz einiger Probleme mit der Lieferung habe ich das Paket wohlbehalten und unbeschädigt doch noch bekommen. Es ist ein wunderbarer 5 l Erlmeyerkolben. Er ist ziemlich schwer, so daß das Glas vermutlich sehr dick ist. Macht einen hervorragenden Eindruck. Ich habe ihn zum Mischen von Füssigkeiten gekauft, funktioniert prima. Kann ich auch wegen des günstigen Preises nur empehlen.

This is well made and works fine as a wine decanter. Easy to clean and provides plenty of surface area for the wine to breathe.

I was a little skeptical how good the glass would hold up because of the low price but it sure did.. Happy and grateful customer

Purchased for making yeast starters for my homebrewing. Have used it directly on my stove top and dunked it straight in to ice water several times and its still in perfect condition. Cleans up perfectly with PBW or oxiclean. Would highly recommend and purchase again if ever necessary.

The flasks themselves are great. However I ordered 3 of them, and 1 of them turned up dirty, as if it had been used before. Has a deposit as if salty water was left to evap in it.Still trying to decide if I will be returning that one. Can't be too careful.That's why I'm only giving 3 of 5 stars. Had they all been clean, it would be 5 of 5.

Arrived on time and packed well. It is clean and looks pro. The bottom is nice and flat and is slightly concave. I think it could be thicker side walls. The top opening, neck and bottom are thicker than the side walls. Great deal for the price. Made in USA.
