  • Dripless, permanent sealing assembly for container
    Patent number: 9625434
    Abstract: An embodiment provides a permanent sealing assembly for a container, such as a reagent bottle. The permanent sealing assembly allows for drip-less reagent container exchange for liquid analysis instruments. The permanent sealing assembly may be integrated into a container, such as a reagent bottle, and provides an outflow tube that extends into the container. The permanent sealing assembly and the outflow tube thereof remain in the container such that, on an exchange of regent containers, a removable cap assembly of the liquid analysis instrument may be affixed to a new container of reagent without the risk of reagent from the old container contacting the surroundings. Other aspects are described and claimed.
