Prepare reliable aqueous, organic, and biomolecular samples with membrane filtration inside a polypropylene (PP) housing. Each housing comes with a color-coded retainer ring seal to prevent leaks and sample loss, and the color helps to visually show you the membrane type inside the housing. Syringe filters have Luer-Lok and Luer-slip connections for easy, quick and tight connections to tubing, syringes, or needles. Filter packs are available in a resealable storage container to enhance cleanliness during multiple opening and closings.
