This specific Nylon membrane is further advantageous as it requires no prewetting, simplifying the filtration process and saving valuable time in a busy lab environment.

The specified pore size of 0.45 µm is a critical parameter, effectively removing particulate matter down to this microscopic level, ensuring the purity of samples destined for sensitive analytical techniques like HPLC. This pore size is a standard for many analytical applications, striking a balance between particle removal and flow rate. The 25 mm diameter provides a substantial effective filtration area of 3.9 cm². This larger area, compared to smaller diameter filters, allows for a higher sample throughput and reduces the pressure required to pass the sample through, thus preventing sample degradation.

Operating within a maximum operating pressure of 4.1 bar (60 psi), these filters are robust enough for most standard syringe filtration applications. This pressure rating ensures that the filter housing will not fail during use, even with samples that might present some resistance. The typical hold-up volume of <125 µL (with air purge) is a standout feature. This minimized volume is crucial for sample conservation, especially when dealing with small sample volumes or expensive reagents, as it ensures that almost all of the filtered liquid is recovered. The sample volume recommendation of <150 mL is a practical guideline, ensuring optimal performance and preventing overload that could compromise filtration efficiency or speed.
