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.

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.

I love my conical flasks( science teacher her) I store oil in them and make my own garlic infused oil, rosemary infused oil. My son said to me I should be worried about what people might think I am " cooking" in my flasks. I told him he should not have watched Breaking bad!

Good value for science level products

Ordered set of 3 flasks, when taking out of small package cut myself on one of the flasks that was broken. No way would I want to return, but not given option of resending broken item which I still require. Seems Amazon dont want to communicate person to person, only by algorith.

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

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

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.

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.
