Why Are the PES Capsule Filters the Good Choice for Critical Liquid Filtration?

In industries where sterility and precision are non-negotiable—such as biopharmaceuticals, healthcare, and vaccine production—the quality of your filtration system directly impacts the safety and integrity of your product. At our company, we proudly offer Sterilisation Filtration PES Capsule Filters that are engineered to meet these exacting demands with superior performance and consistency.

Each of our PES capsule filters is built with a single-layer hydrophilic asymmetric polyethersulfone (PES) membrane, a material known for its exceptional chemical compatibility, high flow rates, and low pressure drops. What truly sets our filters apart is their low extractables profile and minimal protein-binding characteristics, making them particularly suited for the filtration of sensitive biological solutions such as vaccines, monoclonal antibodies, and other high-value proteins.

We understand that in critical filtration applications, reliability is everything. That’s why we integrity test 100% of our capsule filters before they leave the factory. This strict quality assurance process ensures that each unit meets sterilisation-grade performance standards, giving our clients full confidence in both their filtration efficiency and product safety.

The PES membrane technology we use offers broad chemical compatibility, making our filters suitable for a wide range of fluids and processing environments. Whether you’re filtering cell culture media, buffer solutions, or injectable formulations, our capsule filters maintain consistent flow performance and reduce the risk of costly contamination or product loss.

One of the key reasons clients choose our filtration solutions is because we focus not only on membrane quality but also on usability and operational efficiency. The capsule format offers a plug-and-play setup with no need for additional housings, allowing for faster integration into your process and reduced downtime during change-outs.

At our factory, we are deeply committed to helping clients in the life sciences, pharmaceutical, and medical sectors enhance their operations with dependable filtration products. By combining advanced materials, precision engineering, and strict quality control, we deliver PES capsule filters that consistently perform under pressure—literally and figuratively.

If your application requires sterilisation-grade filtration with high throughput and low risk of protein loss, our PES capsule filters are a trusted solution tailored for your needs.
