Sterile Liquid

Choosing the right membrane is critical to the success of liquid sterile filtration within your process. You must choose not only the right pore size, but also media and membrane specifications in order to optimize your yields and product viability.

Sterile Gas

Hydrophobic sterilizing-grade filters are commonly used as air vents on processing tanks. The goal of the application is to maintain near ambient pressure in the tank while ensuring sterility. The tank vent filter removes viruses and microorganisms from the gas as it flows in or out of the tank.

Bioburden/Integrity Testing

Prefiltration is a critical process step that extends the life of your more expensive (final) filter by reducing bioburden and removing unwanted particles earlier in the process. The right prefiltration selection must yield the desired product quality, as well as be the most efficient and cost-effective solution for your application.
