These types of closures are often used in laboratories for sealing test tubes during various procedures, including sample storage, incubation, or when gas-tight sealing is required. The turnover flange design provides additional stability and makes the septa easy to handle during placement and removal. It’s important to note that the choice of septa can depend on the specific requirements of the experiment or procedure, and compatibility with the chemicals or samples involved should be considered.
