1000ml Storage Glass Bottles – 2pcs Round Media Storage Bottle – Borosilicate Glass Bottles – Safe Probe Storage Glass Storage Bottles with GL45 Blue Screw Cap (1000ml - 2pcs)

These bottles are really nice quality. The glass is thick and feels durable, and the measurements on the side are clear and easy to read. The cap seals very well and hasn’t leaked on me at all, which is a big plus when working with liquids. The only downside (not really a fault of the product) is that the bottle is a bit too tall for my smaller autoclave, so I can’t fit it inside. Because of that, I’ve been transferring my media into a smaller bottle for sterilization. That said, for general lab use and mixing, these work great and feel much sturdier than cheaper glassware. Overall, excellent build quality and a solid seal. If you have the space for them in your setup, they’re absolutely worth it. I would definitely buy these again.

Excellent tough bottle with clear markings and good seal despite no rubber gasket.

Incredible look, work great as a punch carrier and powder milk container. Measure lines not fading after many dishwasher, and they work great for measuring adult drinks for parties. Friend dropped a bottle from 4 feet high and no cracking or breaking. Heat resistant and wash great in the dishwasher. 🔥

I purchased an espresso machine. It is strongly recommended to use a water that not only will enhance / improve the coffee taste, but the water also helps to preserve the espresso machine boiler, keeping it limescale free. There are various coffee water recipes on the net. I purchased these to store alkaline buffer and magnesium mix, each. Content from each of these bottles are then added to one gallon of distilled water; to be used in an espresso machine. These bottles are heavy duty; the blue lid closes tightly and does not create a leak when stored horizontally. The ml markings on the bottle are suggestive. By no means they are accurate. I expected that so I utilize a scale for my accuracy needs. 1ml water = 1 gram I recommend these bottles.

These are great little bottles. They are fairly durable, though we did have one break from heat. Not sure if it was a fluke or not. We have ordered several and only had the one that broke. We definitely will continue to buy as needed!
