The filters were primarily used with standard Luer-lock syringes, processing volumes ranging from 5 mL to 50 mL, often with samples that had already undergone initial coarse filtration but still contained fine cellular debris or precipitates.
Under typical laboratory conditions – a controlled temperature and humidity environment – the filters performed exceptionally well. I did not intentionally subject them to extreme conditions like freezing or prolonged high heat beyond their specified limits, as this would be outside their intended operational parameters. The ease of use was a significant factor from the very first attempt. Attaching the syringe to the Luer-lock was straightforward and secure, and the filtration process itself was remarkably smooth. The Versapor membrane’s higher flow rate, compared to some finer pore size filters, meant that I wasn’t fighting against excessive backpressure, which is a common frustration with less efficient filters. There were no immediate issues or surprises; the filters simply performed as advertised, reliably removing particulate matter without visible degradation or loss of sample integrity.
Over several weeks of consistent use, the Pall Acrodisc Syringe Filters with Versapor Membranes, Pall Life Sciences 4459 13 Mm Diameter, Pack of 100 have proven their mettle.

For maintenance, these are disposable filters, meaning there’s no cleaning or upkeep required; once used, they are discarded, which is a significant advantage in a lab setting for preventing cross-contamination. Compared to my past experiences with other brands where some filters might show signs of distress with higher viscosity samples or prolonged use, these Pall filters have maintained their performance. The reliability is exactly what I’ve come to expect from a premium brand, and they continue to meet and often exceed the demands of my daily laboratory tasks.
Breaking Down the Features of Pall Acrodisc Syringe Filters with Versapor Membranes, Pall Life Sciences 4459 13 Mm Diameter, Pack of 100
The technical specifications of the Pall Acrodisc Syringe Filters with Versapor Membranes, Pall Life Sciences 4459 13 Mm Diameter, Pack of 100 are tailored for specific biological research applications. The 0.8 µm pore size is a critical feature, striking a balance between effective particulate removal and maintaining sufficient flow rate. This specific pore size is ideal for prefiltration, removing larger debris that could clog finer filters or interfere with downstream processes, without being so restrictive that it drastically slows down sample preparation. The Versapor (acrylic copolymer) membrane is engineered for high flow rates and low protein binding, which are paramount for preserving the integrity of sensitive biological samples. The 13 mm diameter housing provides an adequate surface area for processing moderate sample volumes efficiently. The Luer-lock design ensures a secure and leak-free connection to syringes, preventing accidental spills or contamination.
These specifications are not just numbers; they translate directly into practical performance. The 0.8 µm pore size is particularly effective for clarifying cell culture media, ensuring it’s free of particulate matter that could inhibit cell growth or clog delicate instruments. The Versapor membrane’s low binding characteristics minimize the loss of valuable proteins or other biomolecules from the sample, a crucial consideration in quantitative analyses. The 13 mm diameter is a good compromise, offering better throughput than smaller filters without the bulk of larger units, making it suitable for routine lab tasks. The Luer-lock connection significantly reduces the risk of sample loss and maintains aseptic conditions, a non-negotiable in cell culture. The fact that they are nonpyrogenic is also a vital specification for any product intended for biological research, ensuring that the filtration process itself does not introduce endotoxins that could confound experimental results.
