Let’s Dive into Pall Acrodisc Syringe Filters, 13mm, Pall Life Sciences 4422 Ptfe Membrane, Pack of 100
The Pall Acrodisc Syringe Filters, 13mm, Pall Life Sciences 4422 Ptfe Membrane, Pack of 100 might not sound like the most exhilarating piece of gear at first glance. However, for those of us in the field who rely on pristine samples and contamination-free environments, they’re absolutely critical. These filters, manufactured by Pall Life Sciences, are designed for filtering gases and organic solvents, as well as providing air filtration and venting capabilities.
My work often involves analyzing water samples in remote locations, from testing the purity of meltwater in the Arctic to ensuring potable water sources in disaster relief zones are safe. Contamination can ruin a sample and render days of work useless, costing time and resources. I needed a reliable, chemically resistant filter that could handle a variety of fluids and environmental conditions.
Upon opening the pack, I was immediately impressed by the individual filter units. The polypropylene housing feels robust, and the luer connections are precise, giving me confidence in a secure fit. Compared to cheaper alternatives I’ve used in the past, these Pall Acrodisc filters have a noticeably higher build quality.
Initially, I was excited to test the chemical resistance of the PTFE membrane, as some of the solvents I work with can be quite aggressive. I anticipated a high level of performance, considering Pall’s reputation and the filters’ price point.
Real-World Testing: Putting Pall Acrodisc Syringe Filters, 13mm, Pall Life Sciences 4422 Ptfe Membrane, Pack of 100 to the Test
First Use Experience
My first field test was conducted during a water quality assessment in a heavily forested area after a major storm event. I needed to filter collected rainwater samples to remove sediment and organic debris before running them through a portable spectrophotometer. Using the Pall Acrodisc filters with a standard syringe made the pre-filtration process incredibly efficient.
The filters performed admirably even in damp conditions, and the 0.45µm pore size effectively removed particulates without clogging too quickly. There was a noticeable difference in the clarity of the filtered sample compared to using less specialized filters I’ve tried. No issues or surprises were encountered during this initial use; the Pall Acrodisc filters performed exactly as expected.
Extended Use & Reliability
After several weeks of consistent use across various field tests, the Pall Acrodisc filters have proven their reliability. Even after filtering several liters of heavily contaminated water, the flow rate remained consistent. I have noticed minimal signs of wear and tear on the polypropylene housing, even after being subjected to rough handling in my field kit.
Maintenance is incredibly straightforward; since they are disposable, there is no cleaning required. Compared to reusable filtration systems, the convenience and reduced risk of cross-contamination offered by the Pall Acrodisc filters are a significant advantage. They have certainly outperformed my previous filtration methods in terms of both efficiency and reliability.
Breaking Down the Features of Pall Acrodisc Syringe Filters, 13mm, Pall Life Sciences 4422 Ptfe Membrane, Pack of 100
Specifications
- The Pall Acrodisc Syringe Filters feature a 13mm diameter, making them suitable for smaller sample volumes. The small size minimizes sample loss and provides a convenient, compact solution for on-the-go filtration.
- These filters utilize a hydrophobic PTFE membrane, which offers exceptional chemical and temperature compatibility. This ensures they can handle a wide range of solvents and aggressive chemicals without degradation.
- They have a pore size of 0.45µm, providing effective removal of particulate matter. This pore size is ideal for pre-filtration prior to instrumental analysis and sterilization of solutions.
- The housing is constructed from polypropylene and includes a female luer lock inlet and male slip luer outlet. These features provide secure and leak-proof connections with standard syringes and other lab equipment.
- These filters are designed with a typical hold-up volume of <30µL, minimizing sample loss during filtration. This is especially crucial when dealing with precious or limited-quantity samples.
- They can withstand a maximum operating pressure of 6.9 bar (100 psi), allowing for rapid and efficient filtration of even viscous solutions. This high-pressure tolerance contributes to faster processing times in the field.
These specifications are crucial because they ensure that the filters can withstand a wide range of harsh conditions and maintain their integrity, providing consistent and reliable performance.
Performance & Functionality
The Pall Acrodisc Syringe Filters excel at their primary function: providing reliable filtration of liquids and gases. They consistently deliver clean, particle-free samples, essential for accurate downstream analysis. The filters’ performance is highly reliable.
The filters’ strength is the exceptional chemical resistance of the PTFE membrane, which allows them to be used with a wide array of solvents. One weakness I observed is that the 13mm size can be limiting when filtering large volumes of heavily contaminated fluids, requiring more frequent filter changes. They meet my expectations overall.
Design & Ergonomics
The Pall Acrodisc filters are designed with ease of use in mind. The polypropylene housing feels solid and comfortable to grip, making syringe filtration simple and straightforward. The luer connections are well-designed and create a secure, leak-proof seal, minimizing the risk of sample loss or contamination.
There is virtually no learning curve; simply attach the filter to a syringe and begin the filtration process. The color coding of the packaging is also a nice touch, helping to quickly identify the correct filter type in a busy lab or field environment.
Durability & Maintenance
Given their construction and intended use, the Pall Acrodisc filters are quite durable. The polypropylene housing can withstand rough handling and exposure to various chemicals. Since the filters are disposable, maintenance is nonexistent, making them a hassle-free solution for filtration needs.
Their single-use design also minimizes the risk of cross-contamination, a significant advantage in sensitive applications.
Accessories and Customization Options
The Pall Acrodisc Syringe Filters do not come with a lot of accessories. They are designed for use with standard syringes. They don’t have a lot of customization options available either.
However, their compatibility with standard luer lock syringes makes them versatile for use with a variety of syringe types and sizes. The filters themselves are available in a range of membrane materials and pore sizes, allowing users to select the optimal filter for their specific application.
