What micron rating should I specify for sanitary liquid filtration?

For most pharmaceutical and beverage streams, 0.2–5 µm absolute-rated cartridges balance sterility and throughput; validate against your worst-case particulate load and CIP cycle.

How do I verify extractables compliance for 316L filter housings?

Require a documented extractables study to USP / and confirm the housing elastomer (EPDM or FKM) is listed in the validation package.

Laboratory Liquid Filtration Systems for KOSA Medical: purity and throughput with 316L stainless steel

How KOSA Medical helps laboratory operators specify 316L stainless steel liquid filtration — purity and throughput with full compliance (ISO 9001, traceability, repeatability).

I've seen a lot in my 15 years at KOSA Medical, but the one constant is the demand for reproducibility and high purity in your labs and R&D facilities. Let's talk about our liquid filtration product line, designed to help you achieve just that. We're talking lab-grade cartridges, sanitary filter housings, and membrane systems that meet the stringent standards of ISO 9001 and ASME BPE 2019. Let me walk you through the key aspects.

Our Commitment to High-Purity Filtration

At KOSA Medical, we understand that contamination can derail even the most meticulously planned experiments. That's why our filtration systems are designed with high-purity applications in mind. We use 316L stainless steel for our housings, ensuring minimal extractables (<1 ppb) and exceptional corrosion resistance. Our cartridges are manufactured in controlled environments to prevent particulate contamination. We maintain strict traceability for all our products, so you can track every component back to its source.

Precision Filtration with Absolute-Rated Cartridges

Precision matters. That's why we offer absolute-rated cartridges with pore sizes down to 0.2 µm. These cartridges provide consistent filtration performance, ensuring that your process fluids meet the required purity levels. Whether you're working with small-bore tubing or larger systems, our cartridges are designed to fit ly into your existing setup. We also offer a range of membrane materials to suit different applications, from hydrophobic to hydrophilic, and everything in between.

Sanitary Design for Repeatable Results

Sanitary design is crucial for repeatability. Our filter housings are designed to meet 3-A Sanitary Standards 2022, ensuring easy cleaning and sterilization. We use polished surfaces and smooth welds to minimize crevices where contaminants can hide. Our designs also incorporate drainage features to prevent fluid trapping, further enhancing cleanability. I've seen firsthand how poor sanitary design can lead to inconsistent results, so we've made sure our products are up to the task.

Case Study: A Contract Development and Manufacturing Organization (CDMO)

A CDMO we worked with was struggling with inconsistent filtration results, leading to batch failures and delayed timelines. After switching to our sanitary filter housings and absolute-rated cartridges, they saw a significant improvement. Their batches now consistently meet the required purity levels, with >99.9% recovery rates. This not only saved them time but also reduced waste, making their operations more efficient and cost-effective.

Custom Solutions for Unique Applications

We know that one size doesn't fit all. That's why we offer custom filtration solutions tailored to your specific needs. Whether you require unique housing sizes, special membrane materials, or specific connection types, we can accommodate. Our application engineers work closely with you to understand your process and recommend the best solution. We've even designed systems for unusual fluids and extreme conditions, so don't hesitate to discuss your application with us.

I invite you to discuss your specific application with our team of application engineers. We're here to help you achieve reproducible, high-purity results, and we'd love to hear about your challenges and goals. Let's work together to find the right filtration solution for your needs.
