SANIpore® PVF Capsule Filter
SANIpore® PVF – PVDF Capsule Filter
The SANIpore® PVF series PVDF capsule filters are ready-to-use, sterilizing-grade devices featuring a single-layer hydrophilic PVDF membrane. They offer broad chemical compatibility and low protein binding, making them well-suited for the final filtration of high-value biological solutions such as vaccines, antibodies, plasma-derived products, and hormone injectables.
Each filter is assembled in an ISO Class 10,000 cleanroom and undergoes 100% integrity testing to ensure batch-to-batch reliability. The high-efficiency PVDF membrane provides a large filtration area, delivering high flow rates with low pressure drop. A durable polypropylene housing ensures structural strength and chemical resistance.

Ordering Information
Common questions about Sanitek
Is the filter suitable for final sterile filtration?
Is the filter suitable for final sterile filtration?Yes. It is validated for bacterial retention and 100% integrity tested, making it suitable for sterilizing-grade applications including final fill.
Is this product single-use or reusable?
The SANIpore® PVDF capsule filter is designed for single-use applications to support sterility assurance and reduce cross-contamination risks.
How should the capsule be installed in a filtration system?
Installation of the SANIpore® PVDF capsule filter is quick and straightforward, requiring no tools. It comes with standard connection options such as hose barb or sanitary fittings, allowing easy integration into existing systems. When installing, make sure the filter is oriented correctly according to the flow direction indicated on the housing. Proper venting during initial wetting helps to eliminate trapped air and ensures full membrane utilization for optimal filtration performance.
What is Stery PVF filter material?
Stery PVF capsule filter is 100% integrity tested, it is constructed of single layer hydrophilic PVDF membrane. It offers broad chemical compatibility, higher filter area with high flow rate at low pressure drop.
What are Stery PVF filters used for?
Stery Hydrophilic PVDF is particularly suited for the filtration of products that contain substances that adsorb to the media, The lower binding characteristics of PVDF make it a good choice for filtration of valuable protein solutions such as vaccines and biologicals.
Sanitek Stery PVF capsule filter with PVDF membrane is suitable for applications such as Bottled water, Vinegar, Aqueous Solutions, Beer, Wine and Spirits, Juice, Soft Drinks, Edible Oils and Pharmaceutical intermediates.
What is the difference between PES and PVDF filter membranes?
The main difference lies in their chemical compatibility and filtration properties. PES (polyethersulfone) membranes offer excellent compatibility with a broad range of solvents, acids, and bases. They are known for their low protein binding and high flow rates.
PVDF (polyvinylidene fluoride) membranes, on the other hand, have superior chemical resistance, making them suitable for aggressive solvents and strong acids. PVDF membranes also provide high protein binding capacity, making them ideal for protein-based applications. The choice between PES and PVDF depends on the specific requirements of the filtration process, including chemical compatibility and protein retention needs.
How do you guarantee the quality of your filters?
All materials meet the specifications for biological safety per USP Class V1-121 C for plastics. Materials of construction comply with FDA regulations for food and beverage contact use as detailed in the US Code of Federal Regulations, 21 CFR. Materials used to produce filter media and hardware are safe for use in contact with foodstuffs in accordance with EU Directives 10/2011.
