Abstract: A vented probe (10) for adding and removing a sample (30) from a container (28) having an opening (32) which is capped with a stopper (34) and a method for adding and/or removing a sample (30) from the container (28) are provided. The probe (10) comprises a hollow, tubular-shaped body (12) having an outer surface (14), an inner surface (16) which defines a lumen (17), and a first end (18) for inserting through the stopper (34) and a second end (20). A sample aperture (22) extends from the outer surface (14) into the lumen (17) proximate the first end (18) of the body (12) and a regulating aperture (24) extends through the body (12) into the lumen (17) proximate the second end (20) of the body (12). A vent passageway (26) is disposed in the body (12) between the first end (18) and the second end (20). The vent passageway (26) allows for venting of the container (28) when the probe (10) is disposed in the stopper (34). There is no direct communication between the vent passageway (26) and the lumen (17). The vent passageway (26) typically includes three spaced-apart grooves which extend longitudinally in the outer surface (14) of the body (12). These grooves each have a sufficient depth and width so that each groove is not occluded when the probe (10) is positioned in the stopper (34).
