These plug style caps are perfect for every size, everyday plastic tubes. These close and seal easier than most plain caps. They also feel as if they create a better seal over just plain caps. These do not work well with glass tubes. When uncapping those, the glass tubes would crack or chip at the top.

A very versatile test tube cap

We started using these caps because an older Tech with diminished strength in her hands was having difficulty taking the lids off and on the BD SST tubes. This cap has really met our needs, she doesn't have difficulty anymore and the other Techs use them regularly now also. They are a universal cap that fits all the tubes in our lab and they stay on evening when the tubes are placed in a bag and laid on their sides. No leakage.
