Glass Erlenmeyer Flask Set, (250 ml, 150 ml & 50 ml) Graduated Borosilicate Glass Erlenmeyer Flasks with Rubber Stoppers & Accurate Scales for Lab, Experiment, Chemistry, Science Studies etc

Nice set of Ehrlenmeyers, with stoppers. They are the usual thickness of glass and ought to last a long time.

Not the toughest but very good flasks. I have had no problem storing my sodium cyanide in one and chloroform in another. Not sure what to do with the smallest yet? Two thumbs

returned didn't need. they were packaged well and the measurements looked good, but needed a beaker instead.

The glass is amazing, both thick and well made. Size is consistent, graduations are correct, and they could pass for genuine American borosilicate.Stoppers are iffy. I’ve had leaks from them, mostly when I open the flasks, and they seem to retain the liquid around the edges of the stopper. That said, they’re perfectly airtight.Great value for the set, and I appreciate the muted look of this brand. Nothing crazy, and they actually do mark the flasks, but it’s not overboard.

Llego en perfecto estado los tres erlenmeyer, ninguna ni fisura ni rotura en alguno de ellos, no mantenían ningún olor en particular y solo queda usarlos más adelante.

Smaller than what I expected, but that's no fault of the product or supplier. I should have paid attention as the sizes are listed. The larger one worked out very well. I will just buy 2 more of just that size in case the original breaks.

Good flasks, packed too close together and not enough padding that resulted in the largest flask(the one I need most) almost completely shattering inside the packaging. The rest arrived in perfect condition though

Very good quality lab equipment.
