MEMBRAcart XL II Filter Cartridges

Reliable Microbial Retention

MEMBRAcart XL II filter cartridges were developed and validated for the beverage industry to provide secure and reliable removal of spoilage microorganisms. The filter medium is a highly efficient polyethersulfone membrane which, in combination with the construction of the MEMBRAcart XL II filter, ensures excellent service life and filtration results.

The MEMBRAcart XL II is an excellent choice as a final filter prior to bottling or storage of beverages and liquid food products.

This filter is integrity testable. An in-situ and non-destructive integrity test can provide assurance of filter performance within minutes. Integrity tests help manufacturers avoid costly issues such as product contamination, product losses, reprocessing and production delays, as well as satisfying auditor requirements.

Specifications
 

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)

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.
