Erlenmeyer Conical Flask with Glass Stopper and Graduation,Borosilicate 3.3 Glass,Lab Glassware,Set of 50ml 150ml 250ml

I needed several small Erlenmeyer flasks with glass stoppers for holding small amounts of volatile and toxic solvents that I use when airbrush painting with epoxy paints. This set is exactly what I needed and I am pleased with the high quality of both the flasks and stoppers. I was a laboratory technician many years ago, and these are the same type of Erlenmeyer flasks we used in Special Chemistry.

Everything went as exspected had no problems or complaints.

I bought the three set of conical flasks with a glass stopper to make facial serums. I wanted something large enough to make several batches at the same time. I needed the construction to be sturdy and have a top. I like the wide bottom design so the containers don't tip over and the small mouth opening so pouring is more controlled. These flasks have been working really well.

the tracking on this is absolutely ridiculous. Weeks now of "left carrier" "arrived at carrier" without any mention of where or any estimates of when. Would not recommend

I only received the 50ml and 150ml flask.

Was extremely well packaged but took about an age and a half to arrive. I am all praise but for the lengthy delivery time. The glass closures fit perfectly so It’s a steal for the money without doubt, well worth the wait!

I use these as bud vases and colored the water in each one and put them in a window along with the stoppers next to its flask. They look unique, artistic, smart, and awesome!

Flasks areade with relatively thick glass, they do not feel flimsy or easy to break. Markings are accurate and stopper has a secure seal. Good quality for the price.
