This ivention is an apparatus for obtaining liquid samples from a fluid flow path (22). The apparatus includes a housing (18) having an access site (23) communicating with the flow path (22), and carrying a piercing member (34) at a location spaced from the access site (23). The housing (18) includes a length adjustable sleeve (32) that allows translational movement of the piercing member (34) toward the access site (23), and into the flow path (22) from where the sample is removed. |
