How do I choose the right size stopper for my laboratory glassware?

When selecting a stopper, measure the opening of your glassware carefully to determine the appropriate size. The Size 7 is generally suitable for openings that measure around 29-30 mm in diameter.

Home Brew Ohio Rubber Stoppers Editorial Review

The Solid Rubber Stopper - Size 7 has received mixed reviews from customers. While some have found it to be a great rubber stopper for certain purposes, others have faced issues with it fitting properly and staying in place. One customer mentioned that the stopper did not fit their size glass jar properly, causing it to pop out easily even when the jar was not full or applying pressure. This made it inconvenient for them to use the stopper for their purified water storage. Similarly, another customer stated that the stopper was not suitable for their 5-8 gallon #7 size glass wine carboys. They were disappointed with how it failed to stay in place and create a secure seal. On the positive side, a customer found a different use for the stopper, using it as a topper for small milkshake shots. They appreciated the cute design and the fact that it created a formidable seal for their specific purpose. In conclusion, the Solid Rubber Stopper - Size 7 has received mixed feedback from users. While it may work well for certain applications like small milkshake shots, it may not be suitable for larger glass jars or carboys where a secure fit is required.
