Flow cells are used for measuring samples with continuous flow as in chromatography or production systems. They are also used in sipper systems where individual samples are aspirated into the cell. Flow cells are made in a wide array of designs because each application has a different compromise of sample volume, flow pattern, pathlength and tubing requirements. We make a wide range of flow cells and have made every effort to simplify the process of selection as much as possible. If you have questions, please e-mail us and we will answer your technical questions promptly.
