Whatman Dia 4 mm Puradisc Syringe Filter, PVDF Media, 0.45 µm

The Whatman Puradisc Syringe Filter is a versatile filtration device commonly used in laboratory settings for sample preparation, clarification, and particulate removal prior to analysis. These syringe filters are available in various sizes, including 13 mm, 25 mm, and 30 mm diameters, to accommodate different sample volumes and flow rates.

Puradisc syringe filters feature a range of filter media options, including regenerated cellulose (RC), polytetrafluoroethylene (PTFE), nylon, and polypropylene (PP). Each filter media type offers specific properties suited for different applications. For example, RC filters are hydrophilic and suitable for aqueous solutions, while PTFE filters are hydrophobic and compatible with organic solvents.

These syringe filters are designed for easy and convenient filtration. They can be attached to standard luer-lock syringes, allowing for quick and efficient filtration of samples directly into vials or other containers. The filters effectively remove particles, microorganisms, and other contaminants from the sample while allowing the desired components to pass through.

Puradisc syringe filters are commonly used in various laboratory applications, including analytical chemistry, pharmaceutical testing, environmental analysis, and microbiology. They are essential tools for achieving clean and reliable samples for downstream analysis or experimentation.

Overall, Whatman Puradisc Syringe Filters offer reliable filtration performance, versatility, and ease of use, making them indispensable for laboratory filtration processes requiring efficient and convenient sample preparation.
