A sample transport device (2) for use in analyzing samples by the headspace analysis technique. The device has a cylindrical platen (4) with counterbored chambers (16) for accepting sample vials (20). The temperature of the platen (4) is controlled by heater (76). The platen (4) is caused to rotate by motor (66) from a first vial transport point to a sampling point having needle (114) and then back for ejection of the sample vial (20). Vertical movement of the sample vials (20) is accomplished by use of elevator rods (88, 104, 120) connected to level winding screws (90 106, 122) mounted below the cylindrical platen (4).

Why it's free to use
- Filed February 25, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 25, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
