My package arrived undamaged, despite being packed in an overly-large box. box with a lid I was extremely fortunate. br>br>However, it's a really nice watchglass! My Corning Pyrex 1 liter beaker is the perfect size!.

I took a chance with the size of my beakers and it turned out to be a success. Because I couldn't find any information on the internet about the recommended beaker lids for the correct ml size beaker, I just estimated it. br>br>I have 600ml beakers, and these lids fit them perfectly. They leave about 4 beakers. The beakers have a 5mm lip all the way around them. They are neither too small to fall in nor too large to get in the way of other items. ALL 600ml beakers: br>br>
- Pyrex, Kimax, and VWR all leave about a quarter of an inch. a lip thickness of 5mmbr> It has a 1mm lip on Pyrex Vista. (It still doesn't fall in, and you can grab the lid, but it's an "exact fit")br>br>I uploaded some photos so people could see how well it fits. I wish I could have had a reference to help me with my purchase. The first two photos are of regular pyrex/kimax/VWR, while the last four are of the Pyrex Vista. br>br>Excellent product! Everything arrived clean, neat, and secure.

I make cosmetics at home and use these to measure dry ingredients, usually polmers, which I add to stirred water. It makes things a lot easier. I try to avoid using disposable items because I want to reduce my waste. Glass products are easier to clean and sterilize, which is why I prefer them.

I needed it for my classroom and found it at a great price. The price is extremely reasonable.
