Let’s Dive into Pallflex Emfab Filters, Pall Life Sciences 7221, Pack of 100
The Pallflex Emfab Filters, Pall Life Sciences 7221, Pack of 100, might not be the sexiest piece of kit in my arsenal, but in the world of environmental science and industrial hygiene, they’re absolute gold. We’re talking about a meticulously crafted filter designed for the demanding tasks of diesel exhaust and stack emission testing. These aren’t your average coffee filters; they are precision instruments engineered for accuracy and reliability when it matters most.
My work often involves assessing air quality in challenging environments, from dusty construction sites to the exhaust plumes of heavy machinery. I needed a filter medium that could consistently and accurately capture particulate matter for analysis, without introducing its own contamination or being significantly affected by ambient moisture. This led me to explore the offerings from Pall Life Sciences, a name synonymous with quality filtration solutions.
Upon unboxing, the Pallflex Emfab Filters exuded a sense of quality. The filters are thin but feel surprisingly robust, owing to the woven glass cloth reinforcement within. The uniformity of the filter discs and the neat packaging spoke to the precision manufacturing processes employed by Pall Life Sciences.
I considered using standard cellulose filters or even quartz fiber filters, but the Pallflex Emfab Filters stood out for their unique combination of properties. The borosilicate glass microfiber construction combined with PTFE bonding promised high purity, low air resistance, and non-hygroscopic behavior – critical for reliable aerosol sampling. The specified water flushing to remove water-soluble residue also gave me confidence in their suitability for demanding applications. These filters offered a degree of reliability and purity that the alternatives couldn’t match, justifying the investment.
My first impression was one of cautious optimism. While filters might seem mundane, the accuracy of my measurements hinges on their performance. These Pallflex Emfab Filters felt like they might just be the reliable workhorses I needed.
Real-World Testing: Putting Pallflex Emfab Filters, Pall Life Sciences 7221, Pack of 100 to the Test
First Use Experience
My initial testing ground was a diesel generator exhaust study at a remote construction site. I deployed the Pallflex Emfab Filters within standard 47mm filter cassettes connected to personal air sampling pumps. The pumps drew a measured volume of air through the filters over an eight-hour work shift.
The filters performed admirably even in the dusty, humid conditions of the worksite. The low air resistance, a key feature touted by Pall Life Sciences, meant that the sampling pumps maintained a consistent flow rate throughout the sampling period, ensuring accurate volume measurements. There were no signs of filter clogging or disintegration, even with the heavy particulate load from the diesel exhaust.
The filters were simple to load into the cassettes; their rigidity, thanks to the glass cloth reinforcement, prevented unwanted tears or creases. A notable observation was the ease with which the filters could be handled for pre- and post-sampling weighing. This is crucial for gravimetric analysis of the collected particulate matter.
Extended Use & Reliability
After several weeks of using the Pallflex Emfab Filters across various air sampling scenarios, I can attest to their consistent performance and reliability. From capturing welding fumes in fabrication shops to assessing particulate concentrations near roadways, these filters have delivered dependable results. There has been no noticeable degradation in filter performance, and the filters remain surprisingly resilient to handling.
Durability has been excellent, with minimal signs of wear and tear even after repeated use in different environmental conditions. The glass cloth reinforcement prevents tearing and maintains structural integrity, making them suitable for use in harsh environments.
Maintenance primarily involves careful handling to avoid contamination and ensuring proper storage in a clean, dry environment. The filters are disposable, so there’s no need for cleaning or regeneration. Compared to my previous experiences with cellulose filters, which often exhibited inconsistent weight gains due to moisture absorption, the Pallflex Emfab Filters have been a revelation in terms of reliability and ease of use. They consistently outperform expectations.
Breaking Down the Features of Pallflex Emfab Filters, Pall Life Sciences 7221, Pack of 100
Specifications
- Size: The filters are 47mm in diameter. This is the standard size for many air sampling cassettes, ensuring compatibility with existing equipment.
- Pall No.: The product’s identifier is 7221. This ensures correct reordering and traceability.
- Unit: They are sold in packs of 100. This is a convenient quantity for research or industrial applications, providing a sufficient supply for multiple sampling events.
- Typical Thickness: They have a thickness of 178 µm (7 mil). This provides structural integrity while minimizing air resistance.
- Typical Filter Weight: They weigh 5 mg/cm2. Knowing the filter weight is critical for accurate gravimetric analysis of collected particulate matter.
- Typical Water Flow Rate: The water flow rate is 32 mL/min/cm2 at 0.35 bar (5 psi). This indicates the filter’s permeability and its resistance to liquid flow.
- Typical Air Flow Rate: They have an air flow rate of 68 L/min/cm2 at 0.7 bar (10 psi). This low air resistance is vital for maintaining consistent flow rates during air sampling, ensuring accurate volume measurements.
- Maximum Operating Temp.: They can withstand temperatures up to 260°C (500°F). This allows for use in high-temperature environments, such as stack emission testing.
- Typical Aerosol Retention They boast an aerosol retention of 99.9%. This high retention rate ensures that nearly all particulate matter is captured by the filter, providing accurate results.
These specifications are important because they collectively contribute to the filter’s ability to accurately and reliably capture particulate matter from air samples. The low air resistance allows for consistent flow rates, the high retention rate ensures accurate capture, and the thermal stability enables use in high-temperature environments.
