Hydrophilic PTFE Syringe Filter 13mm 0.22um/0.45um 100Pcs Lab HPLC Aqueous
Maximize your analytical accuracy with our versatile Hydrophilic PTFE Syringe Filters. Unlike standard hydrophobic PTFE, these specially treated hydrophilic membranes require no pre-wetting and offer universal chemical compatibility. They are the ultimate choice for the simultaneous filtration of both aqueous and aggressive organic solutions, making them indispensable for HPLC sample preparation and critical laboratory 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 demanding 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 safely and efficiently filters both aqueous solutions and harsh organic solvents without the need for pre-wetting.
Minimal Sample Loss: Engineered with an ultra-low hold-up volume (<25 μL), guaranteeing maximum recovery of your valuable small-volume (1-10 mL) samples.
Robust & Leak-Free: Safely housed in an ultrasonic-welded, virgin medical-grade Polypropylene (PP) casing that withstands maximum operating pressures up to 5 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: Designed with a Female Luer Lock inlet and Male Slip Luer outlet for quick, secure, and slip-free attachment to all standard laboratory syringes.
