Starna Flow Cells for Spectrophotometers

Flow cells are used for measuring samples with continuous flow as in chromatography or on-line production monitoring such as tablet dissolution. They may also be used in sipper systems where individual samples are aspirated into and out of the cell either by a syringe or pumping system. A wide variety of flow cell designs are available because different applications require the optimisation of sample availabilty, by sample volume contraints; beam geometry; flow characteristics and path length. Instruments also have differing tube connection requirements relating to the pumping sytem used. The range of flow cells we manufacture is extensive to accomodate the above variations therefore every effort has been made to simplify the process of selection. If you have any questions either technical or otherwise, please e-mail or call us and we will answer your questions promptly.
