A pouring spout for a container, particularly for decantation by pouring, of a liquid phase from the container and formed with a fluid passageway having a screen angularly disposed therein for the removal of solids from the liquid being poured from the container. A vent is provided in the pouring spout to facilitate pressure equalization to minimize or eliminate ebullition.

Pour spout for container with improved pouring feature

A multiple sample needle assembly includes a housing with a chamber therein. A first cannula for insertion into a liquid source is in fluid communication with the chamber. A second cannula is movably positioned in the housing and is out of liquid communication with the chamber when in a first position. A liquid flow mechanism inside the chamber is operatively responsive to inward movement of the second cannula to a second position for allowing liquid to flow from the chamber into the second cannula. After the liquid has been collected, the flow control mechanism automatically returns the second cannula to the first position.

Multiple sample needle assembly

A multiple liquid sample needle assembly is provided which utilizes a housing with a porous filter which is gas permeable and liquid impermeable for providing gas displacement venting for gas displaced by a liquid sample received in the housing. The invention incorporates a translucent or transparent housing for determining whether access to the liquid sample in question has been obtained. The filter of the assembly cooperates with the sequential application of a plurality of vacuum collection tubes to close off passage of air therethrough during the taking of the samples. In addition, the assembly is arranged to accommodate separate I.V. and negative pressure cannulas, or a single cannula with an I.V. and negative pressure point at opposite ends thereof.
