ABSTRACT:
An analytical instrument sample vial positioning and sensor device. A radius or cone-shaped body portion extending below a surface contacts a loosely held sample vial having a flexible septum thereon. The shaped body portion is biased downward resulting in the relative movement between the sample vial and shaped body portion tending to center the flexible septum under the shaped body. A longitudinal bore extending through the shaped body permits the insertion of a syringe needle for the removal of a sample to be analyzed. The pre-positioning of the sample vial presents syringe needles from being bent or broken due to inappropriate alignment with respect to the septum. A sensor is incorporated with the shaped body to detect the presence or absence of a sample vial.
