Real-World Testing: Putting Pall Acrodisc Syringe Filters, 25mm, Pall Life Sciences 4502 Nylon Membrane, Pack of 1000 to the Test
First Use Experience
My initial testing ground was the research team’s mobile lab, set up in a high-altitude base camp. Here, we were processing water samples collected from glacial meltwater streams, filtering out particulate matter and microorganisms for DNA analysis. The Pall Acrodisc Syringe Filters, 25mm, Pall Life Sciences 4502 Nylon Membrane, Pack of 1000 performed admirably, consistently delivering clear, particle-free filtrate even with turbid samples.
We tested the filters under a range of conditions, from near-freezing temperatures to relatively warm, sunny days, and the flow rate remained consistent. The ease of use was also a major plus; the luer lock connections made attaching the filters to syringes straightforward, minimizing the risk of leaks or contamination. There were no surprises, just reliable filtration.
Extended Use & Reliability
After several weeks of continuous use, the Pall Acrodisc Syringe Filters, 25mm, Pall Life Sciences 4502 Nylon Membrane, Pack of 1000 proved to be exceptionally reliable. Even after filtering hundreds of samples, the flow rates remained consistent, and there were no instances of membrane rupture or filter clogging. They performed reliably, delivering consistent purity.
The filters exhibited no noticeable signs of wear and tear, and their polypropylene housing withstood the rigors of field handling without cracking or leaking. Maintaining the filters was also straightforward; pre-filtration of heavily contaminated samples extended their lifespan. Compared to cheaper filters that quickly clogged or degraded, the Pall Acrodisc Syringe Filters, 25mm, Pall Life Sciences 4502 Nylon Membrane, Pack of 1000 clearly outperformed them in terms of both reliability and longevity.
Breaking Down the Features of Pall Acrodisc Syringe Filters, 25mm, Pall Life Sciences 4502 Nylon Membrane, Pack of 1000
Specifications
- Membrane Material: Nylon. This hydrophilic nylon membrane provides excellent chemical compatibility with a broad range of solvents, esters, bases, and alcohols, without requiring pre-wetting. This is crucial for diverse lab applications.
- Pore Size: 0.45 µm. This pore size is ideal for removing bacteria, particulate matter, and other contaminants from solutions, ensuring sample purity. This is essential for sensitive analytical techniques.
- Diameter: 25mm. The 25mm diameter offers a good balance between filtration area and hold-up volume, making it suitable for both small and medium-volume samples. This balance is important for efficient filtration.
- Housing Material: Polypropylene. The polypropylene housing provides chemical resistance and durability, ensuring the integrity of the filter during use. Durability is critical for avoiding leaks and contamination.
- Connections: Female Luer-Lok inlet, Male Luer slip outlet. These standard connections ensure compatibility with a wide range of syringes and receiving vessels, enhancing ease of use. The secure connections prevent accidental disconnections.
- Typical Hold-up Volume: <100 µL. The low hold-up volume minimizes sample loss, especially important when filtering small or valuable samples. Reduced sample loss contributes to accurate results.
- HPLC Certified: Certified for low levels of UV-absorbing extractables, which means they won’t interfere with sensitive analytical measurements. Purity of reagents is paramount.
- Pack Size: 1000. Purchasing in bulk reduces cost per filter and ensures a readily available supply for high-throughput applications. Economies of scale are advantageous.
