PALL 4618 Acrodisc Syringe Filters with Supor® Membrane, Sterile - 0.8 µm, 25 mm (50/pkg)

These syringe filters are used for clarifying and pre-filtering laboratory samples, especially biological fluids, buffers, and culture media. They help remove particulates before analysis, protecting instruments like HPLC systems and improving data accuracy.

The Supor® membrane is made from hydrophilic polyethersulfone (PES), which offers high flow rates and low protein binding. This helps maximize sample recovery while minimizing loss of valuable biomolecules during filtration.

A 0.8 micron filter is ideal for coarse filtration, removing larger particles, cell debris, and aggregates. It is often used as a pre-filtration step before finer membranes to prevent clogging and improve overall filtration efficiency.

Yes, these filters are pre-sterilized using gamma irradiation, ensuring they are ready for immediate use without additional preparation. This is especially important for sensitive biological or microbiological applications.

The 25 mm diameter provides an effective filtration area of about 2.8 cm², allowing efficient processing of moderate sample volumes (typically up to ~100 mL) with fast flow rates and reduced clogging.
