Yopay 4 Pack Glass Media Bottle 1000ml, Reusable Storage Bottles with GL45 Bl...

Excellent quality all around and price was good as well. If you need some of these then this is a good purchase, but I might suggest getting 2 L next time, but that’s for my purposes.

Useful for laboratory

Great for measuring out home made plant based milks. They’re leakproof and fit into the door shelf of the fridge. This is my second purchase of these bottles.

Bottle broke during autoclaving. Never had this happen in my 20+ years of lab experience. Guess these are not the quality glass they pertain to be.

I needed glass 1000ml water to make softened water for my espresso machine (so it never needs to be descaled) and these are really nice! Very good quality, caps fit tightly without leakage.

Doesn’t leak but doesn’t survive heat that well. One literally exploded on me when I added boiling water to it. Other expensive media bottles won’t do this. Just grateful I was wearing my safety glasses. The bottom has a really deep concave making it impossible to be able to use a stir bar if you plan on using these for agar.

Just like the rest, they serve their purpose. Measurements aren't 100% accurate but close enough.

4 nice fit in my hand media bottles

Lids leak if you turn the bottle upside down. Good quality glass

Diese Flaschen gehören ja eigentlich in ein chemisches Labor, aber die haben mir so gut gefallen, daß ich sie auf der Stelle gekauft habe. Ja, und jetzt stehen sie in meiner Küche. Dort sehen gut aus, sind sehr nützlich, und jedesmal wenn ich sie anschaue habe Spaß. Und abgesehen davon, ist eine Küche nicht auch irgend wie ein Labor?

Excellent
