The 7697A Headspace Sampler is the newest headspace technology in Gas Chromatography. This 12-vial Headspace Sampler gives you the exact same hardware and software advantages of its 111-vial counterpart except that it does not have removable vial trays, priority vial positioning, 12-sample oven and bar code reader capability. It is ideal for academic institutions and labs with lower throughput needs and can be upgraded to our 111-vial 7697A Headspace Sampler if your needs change.
