pH Valve Series Online pH Valve 38.3 μL (CAT#: STEM-BC-0443-ZJF)

The pH valve series integrates a flow cell and pH electrode for accurate inline pH monitoring. It provides bypass and calibration operating modes. The valve is suitable for biopharmaceutical and purification workflows that require pH monitoring in the fluid path. It can be used in acid, alkali, and salt media environments. Different connection thread options support system integration. PEEK wetted materials provide chemical resistance. Communication interfaces support automated control and data acquisition. The design enables pH monitoring without changing the fluid path during bypass operation.
