Hydrophobic PTFE Syringe Filter 33mm 0.22um/0.45um 100Pcs Lab Organic Gas Vent
Maximize your laboratory's processing capabilities with our high-capacity 33mm Hydrophobic PTFE Syringe Filters. Engineered with extreme chemical resistance, these non-sterile filters are the ultimate solution for processing large volumes (100-200 mL) of aggressive organic solvents, strong acids, and strong bases. Thanks to their naturally hydrophobic (water-repelling) properties and expanded surface area, they deliver unparalleled performance for high-flow air and gas venting applications.
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, sterile gas venting, and sensitive analytical prep.
0.45 μm: Perfect for general clarification, routine organic 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, ensuring rapid processing of 100-200 mL samples without clogging.
Extreme Chemical Resistance: The Hydrophobic PTFE membrane effortlessly handles highly aggressive organic-based samples, strong acids, and strong alkaline solutions without degrading.
Ideal for Air & Gas Venting: Naturally repels water and aerosols, making it the premier choice for critical venting applications and protecting delicate vacuum or analytical equipment.
Minimal Sample Loss: Engineered with a relatively low hold-up volume (<125 μL) for its large size, guaranteeing maximum recovery of your valuable 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 Female Luer Lock inlet and Male Slip Luer outlet for quick, secure, and slip-free attachment to all standard laboratory syringes.
