Abstract

Liquid sampling apparatus includes a hollow sample intake tube that has an inlet port adapted to receive sample material to be analyzed, and is mounted on a support for movement about a fixed pivot between a reset position and at least two sample intake positions. Also mounted on the support is manually manipulable drive link structure that carries a slider assembly that receives the intake tube. Track structure on the support guides movement of the link structure to slide the slide member along the intake tube between a reset position in which the inlet port is aligned with a waste receptacle, a first sample in which the inlet port extends forward of the slide assembly for insertion into a sample container, and a second sample in which the inlet port is housed in coupling structure carried by the slider assembly and presented to the operator for connection of a transfer device such as a capillary tube.
