Borosilicate Glass Bottles - 2pcs Round Media Storage Bottle - 250ml with GL45 Blue Screw Cap

Nice piece of equipment. Very durable

These 1000 ml graduated borosilicate glass containers are not the best looking ones on the shelf - but they work just as well as the "pretty" ones.Pros: good price, secure lid fit, fits in hand well for a large vessel.Cons: not marked as borosilicate glass, lower weight (thinner glass), graduated only to 900 ml (even if they all do this, I am not a fan).Specs: primary OD ~100 mm, total height ~230 mm, bottle throat ID ~29.5 mm, mass ~508 g (empty w/ cap).

Sturdy bottles, worth the price

It does exactly what was designed to due. When I purchase those liquid non-dairy creamers, sometime the cap will malfunction, so this is my replacement for the creamer containers.

Did the trick

I purchased these for agar work for my lab. I made up my agar by boiling on the stove and dumping into the jar hot. I put the lid on and shook the jar. This was immediately followed by an explosion. The jar burst immediately upon shaking. I have not any problems since with the remaining jar, just do not shake them while they are hot. Do not seal these either when you autoclave them. Will purchase again!

Looks like a good quality bottle. I had two sterilization cycles successfully and on the third one it broke and the agar solution got everywhere and made a huge mess. The cap was very lose with aluminum foil covering the top.

Just what I needed
