EISCO 125mL (4.2oz) Glass Reagent Bottle with Acid Proof Polypropylene Stopper, Borosilicate 3.3 Glass Labs

Purchased this item to store a particularly volatile and toxic liquid cement for plastics that I use for model building. Stuff evaporates in a heartbeat if left open to the air, as well as from all the containers I initially tried, albeit more slowly. This includes the container it's sold in.After trying various containers, and having an entire pint can of the stuff evaporate in the space of a couple of weeks, I decided to go the industrial route and picked up a reagent bottle from a local scientific supply house. Did the trick. No vapors..no evaporation. Have used it for a few years, now. However, I dropped it, broke it, and needed a new one. Ordered this item from Amazon and I'm a happy camper. Glass seems thick and sturdy. Plastic/teflon??...stopper provides an airtight seal. Good product.

Polypropylene cap is great as I can use this to store ABS slurry for 3D printing. Cap works very well, doesn’t melt from acetone and doesn’t let vapor out.

Sturdy and very handy. They seal nicely and so cute on my counter. I use them to mix my essential oils and lotions. I keep going back to buy different sizes.

Very-well packaged for long transport; my purchase of several bottles arrived in pristine condition.And the Teflon stopper fits snugly - my concentrated Nitric does not leak fumes.Thanks for excellent quality production!

Takes a beating, I dropped one on a hard floor, it made a ringing noise but it did not crack or shatter..The design ( width to hight ratio 55/155 = 2.82 ) is good for capacity . I am changing my lab for better effcency, Do you sell in qanity??
