What is pass cell?

Pass cells are cylindrical or rectangular-shaped structures that are used in electrochemical measurements. They are typically made of glass or plastic and have a small opening at one end through which an electrode can be inserted. Pass cells are commonly used in applications that require precise measurement of the concentration of ions or molecules in a solution.

The pass cell works by allowing a controlled flow of the solution through it while the electrode measures the electrochemical properties of the solution, such as its pH or ion concentration. The design of the cell is such that the solution flows through it in a thin, uniform layer to ensure accurate and repeatable measurements.

Pass cells are used in a wide range of applications including in pharmaceutical and food laboratories, environmental monitoring, and biotechnology research. They are also commonly used in quality control processes in industries such as water treatment and chemical production.

Overall, pass cells are essential tools for precise electrochemical measurements in a variety of fields and applications.
