Very good quality
Can take boiling liquid and subsequently crash cooled without cracking. Very robust and the markings are very clear.

good solid flask
This is very sturdy, good quality glassware and I am confident it will survive for many years of brewing, perfect for making up yeast starters.

Great for making yeast starter
Arrived well packaged inside a bubble wrap bag and cardboard box. I'm using it with a magnetic stir plate to make yeast starters for my homebrew. Most brewers use a 2l conical flask for their starters but I decided the 1l was sufficient for the styles of beer I brew. Very happy with my purchase so far. Hopefully it will last me many years.

Great quality flask for many purposes
We bought this for a custom wedding gift to a couple of scientists. It survived a plane flight, laser engraving, being filled with weird stuff and other types of abuse, so it definitely is strong as hell! You could also make funky cocktail glasses from these, or, you know, use them for science, haha.

Does the job for the price.
Decent quality, seem quite thin but i'm sure that's fine, good for the price.

Best option for fast and safe delivery
I’m a science teacher who’s doing little demos at home for tutoring and I needed a set of glassware quite urgently. They packed it very carefully and it arrived with me the next day! Very happy!

Use this for yeast starter for beer making. Perfect size and can be filled with boiling liquid and then plunged into an ice bath with no worries.

Erlenmeyer de bonne qualité, le verre est très épais et il à l'air assez solide. Je n'est pas vérifié les graduations car je ne l'utilise pas pour mesurer des volumes, mais sinon rien à redire, il est top

Perfette, belle, attenzione non si possono utilizzare su fiamma o fonte di calore ma solo utilizzare con liquidi caldi.

Conformi alla descrizione, mi sembrano fatti bene, ma in realtà non li ho usati io.

War als Spaß zu Weihnachten gedacht den Wein so zu dekantieren und ist mittlerweile zum Standard geworden
