  • Automatic test sample handling system
    Patent number: 3985507
    Abstract: An automatic handling system selectively conveys test samples to a test probe for analysis by an instrument. The test samples are contained in sample containers. A magazine contains sampler holders each of which contains sample containers. A transport system conveys the magazine so that the holders successively pass through an extraction station from where the holders can be taken from the magazine and placed back therein. The holders upon extraction are then conveyed past a test probe so that individual samples can be selectively presented to the probe.
