CF II Membrane Cell System Specifications
Operating Parameters
• Effective Membrane Area: 24 inch^2 (155 cm^2)
• Hold-Up Volume: 2.4 oz (70 mL)
• Maximum Pressure:
316SS Cell Body Only 1,000 psig (69 Bar);
Polypropylene and Acrylic Cell Bodies 100
psig (6.9 Bar)
• Maximum Temperature:
316SS Cell Body 350°F (177°C);
Polypropylene Cell Body 180°F (82°C);
Clear Acrylic Cell Body 150°F (66°C)
• pH Range: Membrane Dependent
• Crossflow Velocity: Variable (See graph)
Feed Velocity vs. Flow
Rate
Superficial velocity = Q/(W*T)
Q is the flow rate
W is the width of the flow channel
T is the feed channel height
Connections
• Feed, Concentrate: 1/4 inch FNPT
• Permeate: 1/8 inch FNPT
• Hydraulic Port for Piston: 1/4 inch FNPT
Pumps
• Most lab scale pumps including piston-driven, diaphragm,
peristaltic, centrifugal and gear, are acceptable. Contact Sterlitech
for further recommendations.
Fluid Transfer
• Depending on pressure, standard
tubing or hose can be used for connecting cells to pumps and vessels.
High-pressure hose should be used where the pressure is elevated.
Contact Sterlitech if additional help is required.
