These media bottles have served me very well. They are easy to clean, and extremely durable. I can’t count how many times I’ve dropped them (whether empty or full) only to be relieved to see them fully intact. The threading on the caps is excellent, holds pressure and seals well. The square bottles are very space efficient, but unfortunately can’t be magnetically stirred due to the convex shape of the floor of the bottle. Since they’re only 1L, this is not a serious problem as they can be shaken with ease. I would recommend this product for culture media storage and biological uses, but probably not for chemistry.
