FILTER-LAB® Polypropylene Syringe filters (PP) have their main application in the preparation of aqueous and organic samples, but specially in HPLC dense samples. Its elevated purity guarantees that do not appear weird results on the assays.
Likewise, its excellent resistance and hydrophilic behavior permit its use in aqueous and organic samples.
This kind of filters has raised during its fabrication process a lot of integrity tests with elevated levels of pressure in work.
Our filters are available in non-sterile format and in 13 and 25 mm diameter with 0.22 and 0.45 μm membrane
