General Description The Sterlitech HP4750 Stirred Cell is designed and manufactured to provide many years of trouble-free operation. The HP4750 Stirred Cell is just one of a number of products that Sterlitech manufactures for membrane research and small-scale production. The instruction manual describes the functions, features, configuration, start-up, and operation of the HP4750 Stirred Cell.
Function HP4750 Stirred Cell is a high-pressure chemical resistant stirred cell that performs a wide variety of membrane separations. With a maximum pressure rating of 69 bar (1000 psig), the HP4750 Stirred Cell is ideally suited for reverse osmosis (RO) filtration. The cell also performs nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) separations. Stainless steel construction and chemical resistant components make the HP4750 Stirred Cell an ideal choice to filter aqueous and non-aqueous solutions.
Features In addition to its high-pressure capabilities, the HP4750 Stirred Cell has been specifically designed for ease of use. Some of the unit’s features are:
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 top and bottom are secured to the cell body with easy-to-use mechanical couplings. The design enables low hold-up volume of 1mL to prevent waste of valuable solutions.
STERLITECH? HP4750 1.4.2 High Pressure Operations The HP4750 Stirred Cell can complete a variety of separations from microfiltration to reverse osmosis. The standard cell is designed for safe operation to 69 bar (1000 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 Stirred Cell does not require a pump to supply operating pressure. Pressure regulators and relief valves are available from Sterlitech.
Removable Stir Bar Teflon-coated magnetic stir bar provides agitation to reduce concentration polarization or cake formation typical of “dead-end” or normal filtration. A stirring plate with variable speed settings is available as an option from Sterlitech.
Accepts Standard Membrane Disks HP4750 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, and MF membranes.
1.4.6 Autoclavable All components are fully autoclavable and sterilizable.
STERLITECH? HP4750 2.0 SYSTEM CONFIGURATION 2.1 Major Components FIGURE 1 illustrates the typical configuration of a standard HP4750 Stirred Cell System. The drawing shows the three major components of the system: the Cell Body with removable top and bottom, Stir Bar Assembly, and Standard Coupling. In addition, a source of gas pressure is required to pressurize the cell.
Materials of Construction With 316L stainless steel construction and carefully chosen components, the HP4750 Stirred Cell is extremely resistant to chemical degradation. Buna-N Orings and gaskets are standard; other materials are available as options. The magnetic Stir Bar is Teflon coated. Table 1 in the appendix outlines O-ring and gasket material compatibility.

STERLITECH? HP4750 3.0 PREPARATIONS AND START-UP 3.1 Shipment Verification Verify that the shipment is complete, intact and undamaged. A complete system should include:
stainless steel Cell Body Bar Assembly Coupling O-rings
? Cell ?
Bottom Stainless Steel Membrane Disk
Top Coupling Top Gasket
? Bottom ? Two
? Porous ?
Membrane Loading Insert the O-rings in the bottom of the Cell Body. (Photo 1) Check to be certain that the O-rings fit properly in the grooves. Wet the O-rings with a small amount of water or the fluid to be processed. Place a piece of precut membrane over the center o-ring. (Photo 2) Photo 1 In general, membranes coated on substrate have a shiny, active side and a dull, substrate side. The membrane should be installed with the active side toward the Cell reservoir. If you cut your own membrane, the stainless steel porous disk can be used as a template. Use of a smooth, flat piece of 6 Photo 2
STERLITECH? HP4750 polyethylene as a cutting surface and a single-edged razor blade will allow manual cutting of most membranes. NOTE: Once most membranes are wetted with water or solvent, they should not be allowed to dry in order to prevent performance loss. 3.3 Porous Support Disk Loading Place the stainless steel Porous Photo 3
Membrane Support Disk on top of the membrane to hold the membrane in place. (Photo 3) 3.4 Cell Bottom Insertion Fit the Cell Bottom onto the Cell Body, aligning the circular grooves with the circular ridge on the bottom of the Cell Body. (Photo 4) Use the coupling to clamp the Cell Bottom to the Cell Body. Tighten the high pressure coupling 16 foot pounds of torque or 69 bar (1000 psig) operation. (Photo 5) Photo 5 Photo 4
Stir Bar Assembly Insertion Insert the Stir Bar Assembly by dropping it into the Cell Body through the 2-inch-diameter opening at the top. Figure 2 shows the correct position of the Stir Bar Assembly. After the assembly is in place, pour the solution to be filtered into the Cell Body.
STERLITECH? HP4750 3.6 Cell Top Insertion Insert the gasket on the top of the Cell Body, making sure it fits properly in the grooves. (Photo 6) Secure the Cell Top to the Cell Body with the 2-inch clamp. Tighten the High Pressure Couplings require 16 foot-pounds of torque for 69 bar (1000psig) operation. (Photo 7) After both clamps are properly attached, the HP4750 Stirred Cell should be centered on top of a magnetic stirrer. (Photo 8) Photo 6

STERLITECH? HP4750 3.7 Gas Pressure Source Hook-Up The HP4750 Stirred Cell is activated by compressed air or inert gas pressure source. Attach the High Pressure Hose to the fitting on the Cell Top. Connect the other end of the hose to the pressure regulator assembly on the inert gas supply or the compressed air supply. Photo 9 illustrates installation of the gas pressure source. The compressed air or inert gas source selected will determine regulator style and pressure requirements. Photo 9
OPERATION Pressure Source and Stir Plate Activation Place a Permeate Collection Vessel (user-supplied) under the Permeate Tube. Turn on the magnetic stirrer to start the motion of the Stir Bar Assembly. Gradually pressurize the HP4750 Stirred Cell, checking for leaks. most common causes for leakage. Foreign material on the surface of the seals and insufficient tightening of the clamps are
Separation Completion Upon completion of filtration, turn off the pressure source and depressurize the unit. Slowly open the pressure discharge port allowing the system to depressurize. For low pressure operations (<100 psig), the pressure can be bled off by slightly loosening the pressure feed hose and allowing the pressure to leak out. CAUTION: Do not depressurize the HP4750 Stirred Cell by loosening the couplings. 10
Cleaning The HP4750 Stirred Cell can be cleaned with a variety of cleaners, including detergents, solvents, caustic, acid, enzyme cleaners, etc. Choice of the appropriate cleaning regime should also consider the compatibility of the gasket and O-ring material. For process evaluations where membrane re-use is required, a section of membrane cleaners is presented in section 6.2.2.
