FiberFlo^® Hollow Fiber Capsule Filters

Bacteria, Particle, and Pyrogen Removal*

The unique membrane structure of FiberFlo® HF capsule filters provides consistent and verifiable pyrogen removal* which is superior to traditional, absolute-rated membrane filters. High-level endotoxin, bacteria, and spore removal make these point-of-use filters ideal for a variety of water purification applications.

Longer Lasting

FiberFlo capsules have up to six times the surface area of comparable pleated capsule filters. This larger membrane surface area provides greater capacity and longer life than pleated filters, resulting in lower filter replacement costs.

Easy to Maintain

FiberFlo HF capsule filters can be steam sterilized in-line or autoclaved off-line.

High Flow Rates

FiberFlo HF capsule filters deliver fine filtration at high flow rates with low pressure drops --performance superior to traditional, pleated membrane capsule filters.

Customized

FiberFlo capsule filters are available in three sizes, five micron ratings, and a variety of endcap styles. Both inline and crossflow configurations are available.

Quality Assured

FiberFlo capsule filters are manufactured to medical device quality standards with adherence to GMP manufacturing guidelines. These filters exceed the requirements of USP Class VI Plastics Testing and meet USP XXIII standards for purified water extractables. FiberFlo HF capsule filters are integrity testable by diffusional or forward flow methods.

*The pore size of the FiberFlo 200 is not designed to remove pyrogens.

FiberFlo^® Capsule Membrane Selection

FiberFlo^® 30

FiberFlo HF 30 offers very fine filtration for gas and venting applications. This polypropylene hollow fiber filter has an absolute pore removal rating of 0.03µm. The hydrophobic hollow fiber membrane repells water, but can be wetted by an aqueous solution with high surface tension if prewetted with alcohol.

FiberFlo^® 50

FiberFlo HF 50 offers the highest degree of control of particulates and microorganisms through its absolute pore removal rating of 0.05µm and the retentive characteristics of its Polyphen^TM polysulfone membrane. It is recommended for the most demanding pyrogen removal applications. FiberFlo HF 50 will remove 100 percent of endotoxin when challenged with a feed concentration of 5.0 EU/ml.**

FiberFlo^® 100

FiberFlo HF 100 offers the best balance of flow, pressure, retentive capacity, pyrogen removal, and cost. Its absolute pore removal rating of 0.1µm, and overall pore structure gives high water flow rates and excellent control of particulates, microorganisms, and pyrogens. FiberFlo HF 100 will remove 100 percent of endotoxin when challenged with a feed concentration of 1.0 EU/ml.**

FiberFlo^® 200

FiberFlo HF 200 offers maximum flow rates without loss of bacteria retention. Absolute removal of Pseudomonas diminuta is a characteristic of this filter. The ability of FiberFlow HF 200 to remove bacteria and particulates gives it performance characteristics unmatched by traditional 0.2 micron pleated membrane filters.

**Test sensitivity of 0.06 EU/ml.
