Hydrophilic PTFE Syringe Filter 25mm 0.22um/0.45um 100Pcs Lab HPLC Aqueous
Upgrade your laboratory sample preparation with our high-capacity 25mm Hydrophilic PTFE Syringe Filters. Engineered with a specially treated Polytetrafluoroethylene membrane, these non-sterile filters require no pre-wetting and deliver universal chemical compatibility. They are the ideal, all-in-one solution for processing 5 to 100 mL of both aqueous and aggressive organic solutions, ensuring pristine results for HPLC and general purifications.
Customize your order by selecting your preferred pore size and package quantity from the drop-down menu:
Pore Size:
0.22 μm: Optimal for ultra-fine particulate removal, sterilizing filtration, and highly sensitive HPLC/UHPLC analysis.
0.45 μm: Perfect for general clarification, routine sample preparation, and macro-particulate clearance.
Quantity Options:
100 Pcs / Box (Standard lab use)
300 Pcs (Bulk pack for frequent processing workflows)
500 Pcs (Best value for high-demand analytical facilities)
Universal Compatibility: The hydrophilic PTFE membrane seamlessly filters both aqueous solutions and harsh organic solvents in a single step, saving time and reducing consumable costs.
Optimized for Mid-to-Large Volumes: The 25mm diameter provides a generous 3.9 cm² effective filtration area, ensuring rapid and efficient processing of 5-100 mL samples.
High Sample Recovery: Designed with a low hold-up volume (<100 μL) to minimize the loss of your valuable samples.
Robust & Leak-Free: Safely housed in an ultrasonic-welded, virgin medical-grade Polypropylene (PP) casing that easily withstands maximum operating pressures up to 5.2 bar.
Clear Identification: Each individual filter is clearly printed with the membrane material (PTFE) and pore size to completely eliminate guesswork during busy lab preparation.
Standardized Fittings: Equipped with a standard Female Luer Lock inlet and Male Slip Luer outlet for quick, secure, and leak-free attachment to all laboratory syringes.
