PALL 4611 Acrodisc Syringe Filters with Supor® Membrane, Sterile - 0.1 µm, 25 mm (50/pkg)

These syringe filters are designed for sterile filtration of laboratory samples, including buffers, culture media, and biological solutions. They are commonly used in microbiology, pharmaceutical, and research labs to ensure contamination-free samples before analysis.

A 0.1 micron pore size is used for sterilizing filtration, effectively removing bacteria and even reducing mycoplasma contamination in sensitive samples. This makes it ideal for cell culture and critical biological applications.

The Supor® membrane is a hydrophilic polyethersulfone (PES) material that provides low protein binding, high flow rates, and excellent chemical compatibility (pH 1–14). This ensures maximum sample recovery and efficient filtration performance.

Yes, these filters are pre-sterilized (typically via gamma irradiation) and individually packaged, allowing them to be used without additional preparation. This is essential for maintaining sterility in sensitive lab workflows.

The 25 mm diameter provides an effective filtration area of approximately 2.8 cm², making it suitable for moderate sample volumes (up to ~100 mL) while maintaining fast flow rates and minimal sample loss.
