Description
The Agilent (HP) 7694 Headspace Sampler is an automated headspace sampling system designed for reliable analysis of volatile compounds by gas chromatography. It provides consistent vial heating and controlled sample transfer, helping improve repeatability while reducing manual sample handling. Commonly paired with Agilent and HP gas chromatographs, the 7694 is well suited for routine headspace applications such as residual solvent testing, VOC analysis, and quality control workflows in pharmaceutical, environmental, and industrial laboratories.
Agilent (HP) 7694 Headspace Sampler is offered fully refurbished and tested, in working condition.
Includes:
- Agilent (HP) 7694 Headspace Sampler
- Automated 44-Sample Tray
- 30-Day Warranty Coverage
