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

Used these for an experiment. They held up to high heat for over a week almost nonstop with no damage. Perfect! Plus they look cute and the stoppers work pretty well!

Accurate .

Super cute. Great for costume or decoration. Glass is not thick like pyrex or anything. Rubber cork is a nice touch.

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.

I am creating m own blends of essential oils. These little flasks are perfect for small batch blending.

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.

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

I kept two of the bottles flask that were not broken I return one that broke This is garbage not like Pyrex The problem is they’re so cheap that they can’t even put them in a box They sent it in a paper bag with paper around it. It’s like crazy. I want that bottle replaced
