Reliable sterile filtration for critical process steps

Sterile filtration plays a key role in protecting product quality during sensitive processing steps. DANMIL’s micro and membrane filters are designed for just that, offering dependable retention, steady flow, and strong chemical compatibility for use with liquids or gases. They help remove bacteria, particles, and other fine contaminants without disrupting your process, making them ideal for final filtration or intermediate steps in pharmaceutical production, fine chemical processing, and beverage applications.

Whether you’re filtering at lab scale or in a full production line, these filters support clean and consistent outcomes. Every element is built to meet strict quality and regulatory standards, helping reduce risk and improve control. When your process can’t tolerate contamination, DANMIL’s micro and membrane filters help keep it running safely and smoothly.

Frequently asked questions

Micro and membrane filters are designed for high-precision, sterile-grade applications, such as final filtration of pharmaceuticals or microbial retention in beverages. Process filters, on the other hand, are used for broader particle removal, prefiltration, and utility-level tasks like water, CIP fluids, or chemical separation. The main difference lies in filtration accuracy, regulatory suitability, and sterilization compatibility.

DANMIL offers a wide range of membrane and microfibre media, including polyethersulphone (PES), polypropylene (PP), polytetrafluoroethylene (PTFE), nylon, glass fibre, and PVDF. These are selected based on chemical compatibility, flow requirements, and sterility demands, ensuring performance across both liquid and gas applications.

These filters are used in sterile or critical environments, including biotech fermentation, WFI filtration, beverage final filtration, laboratory setups, and gas venting. Mini cartridges and syringe filters are common in low-volume or point-of-use filtration, while capsules and cartridges are used for inline and final filtration steps in validated processes.

Selection depends on several factors: fluid or gas type, microbial retention requirements, flow rate, temperature, and compatibility with CIP/SIP processes. Speak to a DANMIL expert to evaluate your process and ensure the correct filter media, format, and certifications for your application.
