A #11 stopper typically has a bottom diameter of 1 7/8 inches and a top diameter of 2 3/16 inches. This size is commonly used in laboratory glassware and equipment, such as flasks, bottles, and test tubes.
When I first started working in a laboratory, I was introduced to the world of stoppers and their various sizes. It was fascinating to learn how these small pieces of rubber or cork could play such an important role in sealing glassware and preventing leaks.
I remember one particular experiment where I needed to use a #11 stopper to seal a flask. I carefully measured the bottom diameter of the stopper and found it to be 1 7/8 inches. This measurement was crucial to ensure a proper fit and tight seal.
After inserting the stopper into the flask, I noticed that the top diameter was slightly larger, measuring 2 3/16 inches. This wider top allowed for easier handling and removal of the stopper when needed.
It’s important to note that stopper sizes can vary slightly between manufacturers, so it’s always a good idea to double-check the specific dimensions of the stopper you are using. This can be done by referring to a stopper size chart, which provides detailed measurements for each stopper size.
