MEMBRAcart XL II Filter Cartridges

Traceability

In order to ensure traceability each filter element is marked on the cage with ordering code and batch number. In addition, every filter cartridge bears an individual number. Product name, removal rating, ordering code and batch number are indicated on the packing label. 

 

Typical Titer Reduction¹

Removal Rating	Test Organism	Titer Reduction
0.2 μm	Brevundimonas diminuta	>1010
0.45 μm	Serratia marcescens	>109
0.65 μm	Saccharomyces cerevisiae	>1010

 

Materials of Construction

• End Caps: Polypropylene
• Cage: Polypropylene 
• Drainage / Support Nonwoven: Polypropylene
• Filter Membrane: Polyethersulfone (Hydrophilic)
• Core: Polypropylene
• Adapter: Polypropylene (Stainless steel ring in adapter 7, 8 and 41)
• O-ring Seals: Silicone elastomer

 

All construction parts of the MEMBRAcart XL II filter are thermo-plastically welded, that means no adhesives are used.

Typical Flow Rate / Pressure Drop

Typical flow rate per 254 mm (10in.) element for clean water

 

Maximum allowable Differential Pressure

The maximum allowable differential pressure in a forward flow direction for MEMBRAcart XL II filters is shown in the table below.

Temperature	Max. allowable Differential Pressure2
Up to 40 °C (104 °F)	500 kPa (5 bard) (72.51 psid)
40 °C to 80 °C (104 °F to 176 °F)	300 kPa (3 bard) (43.51 psid)

 

Sterilization and Sanitization

MEMBRAcart XL II filters can be repeatedly steam-sterilized or autoclaved in situ, or they can be sanitized with hot water.

Medium	Temperature	Max. allowable Differential Pressure	Cumulative Time3
Steam	125 °C (257 °F)	30 kPa (0.3 bard) (4.4 psid)	50 hours4
Hot water	85 °C (185 °F)	250 kPa (2.5 bard) (36.3 psid)	50 hours

¹The typical titer reduction is determined in laboratory liquid challenge tests on 10 in. filter
²In fully compatible fluids which do not chemically attack, soften or adversely affect the filter in any way.
³Measured under laboratory test conditions. The actual cumulative time depends on the process conditions.
⁴Note: 35 hours for 0.2 μm MEMBRAcart XL II filter cartridges.
