Hydrophilic PTFE Syringe Filter 33mm 0.22um/0.45um 100Pcs Lab HPLC Aqueous
Maximize your laboratory's processing power with our high-capacity 33mm Hydrophilic PTFE Syringe Filters. Specially treated to be hydrophilic, these versatile, non-sterile filters require no pre-wetting and offer universal chemical compatibility. They are the ultimate solution for the rapid, single-step filtration of large volumes (100-200 mL) of both aqueous solutions and aggressive organic solvents, ensuring pristine sample preparation for HPLC and critical analytical workflows.
Customize your order by selecting your preferred pore size and package quantity from the drop-down menu:
Pore Size:
0.22 μm: Optimal for sterilizing filtration, ultra-fine particulate removal, 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 continuous processing workflows)
500 Pcs (Best value for high-demand analytical facilities)
High-Volume Processing: The large 33mm diameter provides an expanded 4.5 cm² effective filtration area, effortlessly handling high sample volumes (100-200 mL) without clogging.
Universal Compatibility: The hydrophilic PTFE membrane seamlessly filters both aqueous solutions and harsh organic solvents without the need for pre-wetting, saving you time and reducing consumable costs.
Minimal Sample Loss: Engineered with a low hold-up volume (<125 μL) relative to its large size, guaranteeing maximum recovery of your samples.
Robust & Leak-Free: Safely housed in an ultrasonic-welded, virgin medical-grade Polypropylene (PP) casing that 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: Designed with a standard Female Luer Lock inlet and Male Slip Luer outlet for quick, secure, and slip-free attachment to all laboratory syringes.
