Bleed Valve Assembly for HP4750(X), 2500 PSI

Unique Design: The top of the cell is easily removed to fill the vessel with up to 300 mL of solution. The bottom is removable for easy membrane change-out. The design enables low hold-up volume of 1mL to prevent waste of valuable solutions.

High Pressure Operations: The HP4750 (X)Stirred Cell can complete a variety of separations from microfiltration to reverse osmosis. The standard cell is designed for safe operation to 69bar (1000psig) (HP4750X: 172 bar (2500 psig)).

Inert Gas Pressure Source: Standard sources of compressed air or inert gas allow variable, safe, and consistent supply of pressure to perform separations. Volatile solutions can be processed safely because of HP4750(X) Stirred Cell does not require a pump to supply operating pressure. Pressure regulators and relief valves are available from Sterlitech.

Mechanical Stirring Mechanism: Sterlitech can provide an optional mechanical stirrer to be used with the HP4750 (X).

Accepts Standard Membrane Disks:  HP4750 (X) Stirred Cell accommodates any 47-50 mm diameter membrane disk. For convenience, Sterlitech offers precut and packaged membranes in single type or assortment packs, from a wide selection of RO, NF, UF, MF, FO, OSN, and MD membranes.

Autoclavable: All components are fully autoclavable and sterilizable.
