Yopay 10 Pack Media Storage Bottles with GL45 Blue Screw Cap, 250ml Reusable Glass Bottle, Round Scientific Glass Container for Labs, Classrooms or Home Use

This is my initial review on the day I received my box of 10 bottles on 08-08-2024. As I delve into amateur chemistry I’m finding the need to store more chemicals as I synthesize them. The size is great for chemicals that you won’t be needing or creating in bulk. The jars are fairly large and very sturdy. So far I’ve only used one with a synthesized chemical and I tested for leakage with water on another in the pack. The lids are a nearly perfect (very slightly smaller) 2 inch round “about 50mm” which works out great if you want to use a 2 inch label for the lid. So far, so good. You can’t beat the price. (About $2.20 U.S. per bottle in a 10 pack after tax on this date). I will be testing the durability, with my biggest concern being the lids ability to withstand strong acids and oxidizers, and I will update my review periodically.

Works as advertised seals work great exactly what I needed

For the money, these are pretty amazing. Came packaged with each bottle in it's own foam pocket to prevent breakage. Survived autoclaving and don't drip when poured. Not often am I impressed with a product nowadays with everything seeming to be disposable chinese garbage, but I highly recommend these.

The glass is thick and the plastic is super resistant to acids like fuming nitric and concentrated sulfuric acid. As well as many other chemicals. I have never got this good on deal on storage bottles. I would recommend 100% even if it's not for chemistry they're very well made. I couldnt find out what type of plastic the lid is but it's chemical resistant for sure

Great bottles for sharing things with friends

I love these bottles! I purchased another box because I use these for juicing.

Great bottles for the price. Be sure to tighten them well, they aren't perfect. But they do the job.

Perfect 👌
