A sampling port comprising: a body (206, 301) having an exterior surface extending between a first end face and an opposing second end face, the body (206, 301) bounding a first passage and a second passage each extending between the first end face and the second end face; a support tube having an interior surface bounding a first passageway extending between a first end and an opposing second end, the second end of the support tube being coupled with the first end face of the body (206, 301) so as to communicate with the first passage, the first end of the support tube being sealed closed; a sampling tube having an interior surface bounding a second passageway extending between a first end and an opposing second end, the second end of the sampling tube being coupled with the first end face of the body (206, 301) so as to communicate with the second passage, at least a portion of the sampling tube being connected to the support tube; a flange (58, 208) encircling and radially outwardly projecting from the body (206, 301); characterised in that the sampling port further comprises: an elongated collection tube having an interior surface bounding a third passageway extending between a first end and an opposing second end, the first end of the collection tube being coupled with the second end face of the body (206, 301) so as to communicate with the second passage; or the support tube, the sampling tube, and the body (206, 301) are integrally molded as a unitary member. a body (206, 301) having an exterior surface extending between a first end face and an opposing second end face, the body (206, 301) bounding a first passage and a second passage each extending between the first end face and the second end face; a support tube having an interior surface bounding a first passageway extending between a first end and an opposing second end, the second end of the support tube being coupled with the first end face of the body (206, 301) so as to communicate with the first passage, the first end of the support tube being sealed closed; a sampling tube having an interior surface bounding a second passageway extending between a first end and an opposing second end, the second end of the sampling tube being coupled with the first end face of the body (206, 301) so as to communicate with the second passage, at least a portion of the sampling tube being connected to the support tube; a flange (58, 208) encircling and radially outwardly projecting from the body (206, 301); characterised in that the sampling port further comprises: an elongated collection tube having an interior surface bounding a third passageway extending between a first end and an opposing second end, the first end of the collection tube being coupled with the second end face of the body (206, 301) so as to communicate with the second passage; or the support tube, the sampling tube, and the body (206, 301) are integrally molded as a unitary member. an elongated collection tube having an interior surface bounding a third passageway extending between a first end and an opposing second end, the first end of the collection tube being coupled with the second end face of the body (206, 301) so as to communicate with the second passage; or the support tube, the sampling tube, and the body (206, 301) are integrally molded as a unitary member.
