An apparatus for inoculating a sample to or withdrawing a sample from a vessel or conduit includes a body with an internal sample cavity, a valve operating rod movable to open and close an orifice to the sample cavity and a coupler to attach the body to a port of the vessel or conduit. A portion of the sample cavity is formed by an endcap which includes the orifice. The sample cavity is thermally and/or electrically insulated from the vessel or conduit. This insulation can arise from an empty or filled space between an inner wall and outer wall of the valve. Otherwise, insulating material can be used in forming the valve. The valve can be mountable on the vessel or conduit such that a positive drain angle is maintained regardless of whether the ferrule to the vessel or conduit is inclined upwardly, downwardly or is horizontal.

[ What is claimed is:] [1.] A valve for use with a vessel or conduit, the valve comprising:a sample orifice on a front end thereof, the front end of the valve being penetratable into the vessel or conduit such that the orifice is within and non-flush with an interior wall of the vessel or conduit, when the valve is mounted on the vessel or conduit, an area of the valve around the orifice being positionable in the vessel or conduit and being insulated such that an internal cavity of the valve is insulated from an ambient environment within the vessel or conduit. [4.] A valve comprising:a drain passage;a collection chamber, the drain passage being operatively connected to the collection chamber;an orifice at a front of the collection chamber;a bottom of the collection chamber forming a path which extends from the orifice to the drain passage, the path continuously declining from the front of the collection chamber to the drain passage and is free from undraining recesses such that flow through the collection chamber is unobstructed; anda device for detachably mounting the valve to a vessel or conduit,wherein no pooling of material occurs in the bottom of the collection chamber.
