Memtrex MP-B

Summary

Product identification

Memtrex* MP-B (MMP-B) filters are pleated filters featuring a Hydrophilic Polyethersulfone (PES) membrane, specifically designed for beverage applications. They offer low protein-binding, high flow rates, and high throughputs. Every filter is 100% integrity tested.

Operating limits

• Maximum Forward Differential Pressure: 60 psi (4.1 bar) @ 70°F (21°C)
• Maximum Reverse Differential Pressure: 30 psi (2.1 bar) @ 70°F (21°C)
• Maximum Operating Temperature: 180°F (82°C) at 10 psid (0.7 bar) in water

Product water

• Memtrex MP-B filters meet US FDA requirements for food contact under applicable regulations in 21 CFR.
• Filters meet the test criteria for USP Class VI-121°C Plastics.
• Aqueous extracts contain less than 0.25 EU/ml.
• Typically exhibit low levels of non-volatile residues.

Integrity Testing (Air diffusion per 10” module after saturation with clean water):

• 0.2 µm: ≤ 19 cc/min at 30 psi (2.07 bar)
• 0.45 µm: ≤ 16 cc/min at 20 psi (1.38 bar)
• 0.65 µm: ≤ 12 cc/min at 13 psi (0.90 bar)

Applications

Memtrex MP-B filters are specifically designed for beverage filtration, including final filtration of:

• Wine
• Beer
• Fruit Juices
• Bottled Water
• Liquor
• Fountain drinks

Additional Information

• Filters may be autoclaved or in situ steam sterilized up to 257°F (125°C) in 30-minute cycles for a maximum accumulated exposure of 10 hours.
• Alternatively, filters may be sanitized with compatible chemical agents.
• Users should carefully verify chemical compatibility, as conditions vary with each application.
