Yizerel 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.

Good value for science level products

Very pleased with the quality and (machine) workmanship on these for the price.I thought I'd have to pay at least £10 a piece of average quality glass lab wear but these are perfect for my needs.They are perfectly formed and well balanced. So stand perfectly on their own (no odd unbalancing lumps that may be expected from such low price lab glass).They work great on a magnetic stirrer with the bungs in the top to prevent any escaping liquid or any external contaminants.The liquid measure on the side is even very accurate, marching up perfectly with my measuring cylinders and also from syringe measured liquids.Overall I'm very glad I chose these.

The media could not be loaded. Good value for money, unfortunately one of the vessels arrived broken, I don't need all three of them so can't be bothered returning, just letting you know you might consider changing delivery method.

Would’ve been 5* but the largest one came broken! They need more padding protection during transit. Other 2 are all good though

Item came smashed !!

I have used these with some extremely strong chemicals! Works great!

They are what the are. The stoppers are not great. But. Cheap.

The rubber stoppers stink really bad, and the first time I used them they absorbed the fumes from chemicals, so now they're even worse. I'd recommend buying a set with glass stoppers, or, if you don't need stoppers just chuck these rubber plugs as soon as you get them. You'll thank me later.
