Syringe Filters PTFE Membrane – Hydrophilic Filtration – 0.22um Pore Size, 25mm Membrane Diameter

🛡️ Precision Filtration for Sterile Success

These 25mm syringe filters feature a 0.22µm PTFE (Hydrophobic) membrane, making them the gold standard for mushroom cultivation. Whether you are filtering liquid culture (LC), creating sterile air vents for jars, or performing sensitive laboratory transfers, these filters ensure total biological isolation – while maintaining the legendary chemical inertia and heat resistance of Teflon.

Choose Your Sterility Level:

1. SafeSteri Premium (Ready-to-Use): We understand that not everyone wants to fire up a pressure cooker for a single filter. Our SafeSteri units are individually hand-wrapped in heavy-duty foil and professionally autoclaved at the STS Testing Station. They arrive sterile and protected, ready to be unwrapped directly inside your Still Air Box or in front of your Flow Hood.

2. Bulk Unsterile (Lab Ready): For high-volume labs, our bulk packs offer the best value. These are factory-fresh and clean but must be sterilized before use in sterile applications. PTFE is naturally heat-resistant and handles standard autoclave cycles (121°C) with ease.

Key Features:

• Hydrophobic PTFE: Unlike Nylon filters, these will not “wet out” or clog when exposed to moisture, making them ideal for gas exchange and LC work.

• Standard Luer Lock: Fits all standard medical and laboratory syringes.

• 25mm Diameter: Offers a larger surface area for faster flow rates and less hand-pressure during filtration.

• 0.22µm Pore Size: Medical-grade barrier against bacteria, yeast, and mold spores.

• pH Range 1-14: Extremely stable, won’t degrade even when used with aggressive cleaning agents or specialized nutrient solutions.

• PP Housing: Encased in high-quality Polypropylene, designed to withstand the heat and pressure of repeated autoclave cycles without cracking.
