Irenare Media Storage Bottles Borosilicate Storage Glass Scientific Round Graduated Media Bottle with Blue Gl45 Screw Cap for Lab Water Reagent Liquids(500 ml,8 Pcs)

Llegaron en una caja mas grande y con bastante protección, todas intactas. Excelente producto y entrega rápida.

Well-made borosilicate bottles with GL45 lids. They arrived quickly and were very well packed - top 10% of things I've purchased regarding packaging. Although they were packed as if they were the most fragile product on Amazon (a compliment), these are some of the sturdiest bottles I've purchased. The glass is sufficiently thick to survive a small drop even. The design is good - a bottle is a bottle but the mouth is large enough to use a spatula to add a reactant or use most pipettes. The lid fits snugly and is waterproof and seemingly gas-resistant to a good degree. I'm using one to hold a liquid sensitive to the air and it doesn't seem like there's any degradation while stored out in the open. The price was great and I think I'll be buying more in the near future.

العبوات جيدة ولكن ارجو تغليفها بشكل جيد لمنع تكسرها وصلت العبوات ووحدة مكسرة بشكل كبير مفتتة

Haven't dropped them or anything, but they seem sturdy. Caps fit nicely. I uses them for short-term storage of boiling raw ginger tea and batch raw boiling coconut water from the coconuts. Not exactly like canning, but I put the cap on loose, let cool some, tighten and put in fridge. I dunk the bottles and caps in boiling water right before. So far have had success with cold storage of a few weeks.

Buen producto de buena calidad
