Pressure Vessels for High-Purity Chemicals

Dispense Chemical With Absolutely No Pulsation


White Knight’s PTFE and PFA pressure vessels provide laminar flow at the point of use and serve as chemical holding or mixing tanks. They are available in 4-inch diameters and in various connectable pipe lengths. They feature configurable port connections, and PTFE manifold ends can be designed with more ports or integrated valves. Capacitive sensor ports for high- and low-liquid levels are standard. Mid-liquid level sensing adapters are also available.
