These are definitely great bottles for storing chemicals but they are missing the cap seals. They came with the pour ring that attaches to the bottle but the Teflon seal that actually attaches to the cap is nonexistent. But other than that quality product.

These bottles have thick glass and arrived packed well with no cracks or breaks. I'm very happy with these bottles.

The bottles are nice and all but they leak quite a bit and are definitely not close to airtight (allow a lot of evaporation) nor leakproof.For storing volatile chemicals these are absolutely a no-go. Spend the extra money and get real Pyrex ones made in the EU.

UPDATE: Return was smooth and easy. Seller had perfect replacement at my door within 2 days. Excellent experience! I use these bottles to create and safely store caustic chemicals in solution. So far; so good!

I can't believe there are zero reviews on these bottles. So far I have bought one package of each of the sizes except the 100mL. Each one of them are equally incredible. They are pricey, absolutely. But then, all amber borosilicate bottles are going to be. These are 100% worth the cost. They are very thick, so much so that I was surprised by the weight when I first picked them up. It feels like the entire wall is at least 4mm or 5mm thick. The amber color is equally as impressive as the rest. The pictures on the listing look like they have a spotlight shining through them. At normal light levels they appear almost black. You can still see liquid levels easily enough though. And the graduations are really like the icing on the cake here. I haven't verified their accuracy, but really they should only be used as an estimate anyways. IDK if they have changed the model slightly or if the pictures just look weird, but the lids are quite a bit bigger than they appear. The mouth is about half dollar sized and the caps are very large.TL;DR BUY THESE! They are great storage bottles. Oh, they are also shipped competently. They come packed in nice soft, cut out foam blocks.

These are a little pricey for what I needed but they are definitely better than another brand that I returned. These come excellently packaged to avoid damage during shipping. Even at this price, I will definitely order again if I end up needing more.

Claimed to be sealed reagent bottles. The bottles are unusable as all 4 leak solvent when filled. Spend the extra money and go with a name brand unless a slight leak is acceptable for your project. Did not have issues with the 1000ml Pyrex reagent bottles.

Not every GL45 media bottle is high quality, but these are really good. The tint of the glass is nice and dark, the anti-drip rings fit the bottle really well, and I haven't had any that leaked. All of them arrived unbroken. I was hesitant to buy a case because I really didn't need that many bottles, but I'm glad I did. I saved a few dollars buying the case quantity instead of individual bottles and the quality of the product is great.
