Rocwing - Borosilicate 3.3 Glass Graduated Conical Erlenmeyer Flask for Laboratory (50ml, 2 in a pack)

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.

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.

Very quick delivery, and a quality item.

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!

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.

Good quality item.

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

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.

Arrivo puntuale. Vetro robusto. Io lo uso per l' olio. Si adatta perfettamente al mio dosatore.

Rien à redire. Très bon rapport qualité/prix. Solide, finition impeccable. Arrivé beaucoup plus vite que prévu en plus.

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

Buon prodotto, certo non sono precisissime ma il materiale è buono.
