Let’s Dive into Pall AcroPak 500, 1000, and 1500 Filter Capsules, Sterile, Pall Life Sciences 12995 Acropak 500 Filter Capsules
The Pall AcroPak 500, 1000, and 1500 Filter Capsules are sterile filtration devices designed for laboratory use, specifically large volume media preparation and pilot-scale manufacturing. Manufactured by Pall Life Sciences, these capsules utilize Supor (hydrophilic polyethersulfone) membranes, known for their high throughput and fast flow rates. The key feature of these filters is their ability to handle volumes ranging from 50L (AcroPak 500) to 150L (AcroPak 1500), making them versatile for various applications.
My need for these filters stemmed from a persistent challenge in our pilot-scale biopharmaceutical production: inconsistent sterile filtration. We were losing batches due to slow filtration times and concerns about maintaining sterility throughout the process. I chose the Pall AcroPak because of Pall’s reputation for quality and the integrated prefilter design, which promised higher throughput with our complex biological solutions.
Unboxing the AcroPak 500, my initial impression was one of robust construction. The polypropylene housing felt durable, and the fusion-welded seams inspired confidence. Compared to our previous filters, which relied on adhesives, the AcroPak felt significantly more reliable.
I considered Sartorius Sartopore 2 and Millipore Stericup filters. Ultimately, I chose the AcroPak for its larger filtration area options (up to 1500 cm²) and the integrated prefilter, features not uniformly available in the other brands’ comparable models. I was optimistic that the AcroPak would resolve our filtration bottlenecks.
My first impression was excitement mixed with a healthy dose of skepticism. Could this relatively simple capsule truly address the complexities of our sterile filtration needs?
Real-World Testing: Putting Pall AcroPak 500, 1000, and 1500 Filter Capsules, Sterile, Pall Life Sciences 12995 Acropak 500 Filter Capsules to the Test
First Use Experience
I initially tested the AcroPak 500 in our cell culture media preparation lab. The aim was to filter 25L of complex media containing serum supplements. Previously, this process took upwards of 2 hours with our old system, often requiring multiple filters due to clogging.
Under standard lab conditions (around 22°C and controlled humidity), the AcroPak 500 completed the filtration in just under 45 minutes. This was a significant improvement. I observed no signs of leakage or pressure drop during the process, and the sterile vent plug functioned flawlessly.
The ease of use was noteworthy; the tapered hose barb connections made setup straightforward. There were no unexpected issues during the first use.
Extended Use & Reliability
After several weeks of consistent use across multiple batches of media (ranging from 25L to 50L), the AcroPak 500 has held up exceptionally well. There have been no instances of membrane failure or loss of integrity. The polypropylene housing shows no signs of stress or cracking, even after repeated autoclaving cycles.
Maintenance is minimal: a simple flush with sterile water after each use is sufficient. This ease of maintenance is crucial in a high-throughput lab environment. Compared to our previous filters, which required meticulous cleaning and often degraded quickly, the AcroPak has been a clear upgrade. It consistently outperforms our old system in terms of both speed and reliability.
