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

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.

The set arrive well packed. It is great to have the stoppers sized for each flask.

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.

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

Very good quality lab equipment.

Stoppers are not the same colour and one looks used quality.

Bought these for a photo shoot and they’re great. I love the different sizes and it looks high-quality.
