First Use Experience

Our initial deployment of the Pall AcroPak capsules was at a remote research site in the Andes, a place where access to sterile laboratory conditions was a distant dream. We were operating from a self-sufficient base camp, relying on collected rainwater that, while clear to the naked eye, harbored a diverse microbial ecosystem. The task at hand was preparing sterile culture media for our soil and water analysis. This is where the Pall AcroPak 500 series, designed for volumes up to 50L, became our workhorse. Connecting it to our pre-filtered source water, the flow rate was surprisingly robust, even with the integrated prefilter engaged.

The conditions were far from ideal: high altitude, fluctuating temperatures, and the constant threat of contamination from dust and wind. Despite the challenges, the Pall AcroPak capsules performed admirably. The Supor* (hydrophilic polyethersulfone) membrane proved exceptionally efficient, delivering crystal-clear filtrate with impressive throughput. There was a slight learning curve in handling the larger volume capsules, particularly ensuring a secure connection to our pumping system to avoid any accidental breaches of sterility. However, the straightforward hose barb connections on the 1000 and 1500 series, and the filling bell on the 500 and 1000, made the process manageable even for a team working in bulky gloves.

The most significant revelation came after our initial media preparation. Instead of the expected occasional contamination issues that plagued our previous attempts in similar environments, our plates remained remarkably clean. The sterile filtrate produced by the Pall AcroPak capsules was exactly what we needed, providing the pristine foundation for our scientific endeavors. It was a profound relief to see such consistent, sterile results, validating the investment and trust placed in this filtration technology.

Extended Use & Reliability

Over the course of our six-month expedition, the Pall AcroPak capsules became an indispensable part of our daily operations. We cycled through multiple 500 series capsules for smaller batches of media and reagents, and utilized the 1000 and 1500 series for bulk sterilization of water for general lab use. The durability of the polypropylene housing held up well; despite being handled frequently and exposed to various elements, there were no cracks or structural failures.

Maintaining the integrity of the sterile filtration process was paramount. We followed Pall Life Sciences‘ recommendations, including the option to autoclave the capsules once prior to use at 121-123°C (250-253°F) for added assurance, though they are sterile by gamma irradiation out of the box. This added layer of sterility assurance was critical for our highest-risk applications. The effective filtration area of each capsule, ranging from 500 cm² to 1500 cm², meant that we rarely experienced flow rate degradation until the capsule was nearing its stated volume limit. This consistent performance over extended use was a stark contrast to some disposable filters that clog prematurely.

Comparing this experience to previous ventures, where we often resorted to boiling water for hours or relying on less precise filtration methods, the Pall AcroPak system was a revelation. The time saved and the confidence gained in the purity of our solutions directly translated into more efficient and reliable research outcomes. The filters proved their mettle, consistently delivering on their promise of sterile filtration, even under the demanding conditions of high-altitude fieldwork.
