Syringe filter is a single-use, membrane-based cartridge designed for fast, efficient, and cost-effective filtration of small-volume liquid or gas samples (typically \(\le 100 \text{ mL}\)). Attached to a syringe via Luer-lock fittings, it removes particles, contaminants, or microorganisms, improving sample purity before analysis or sterilization.Key Features and ComponentsComponents: Consists of a plastic housing (often polypropylene) and an internal membrane filter.Filter Mechanisms:Hydrophilic: Good for aqueous solutions.Hydrophobic: Good for organic solvents and venting applications.Pore Sizes: Common sizes include \(0.22\ \mu\text{m}\) (for sterile filtration/removing fine particles)
