Breaking Down the Features of Pallflex Emfab Filters, Pall Life Sciences 7217, Pack of 100
Specifications
The technical specifications of the Pallflex Emfab Filters, Pall Life Sciences 7217 are where their true value lies, especially for demanding analytical applications. These filters are constructed from pure borosilicate glass microfibers, a material known for its chemical inertness and thermal stability. This is further reinforced with a woven glass cloth, providing structural integrity and preventing the delicate microfibers from being dislodged. The entire composite is then bonded with PTFE, enhancing its chemical resistance and ensuring filter purity.
These specifications directly translate into tangible performance benefits. The 37 diameter size is standard for many air sampling applications, ensuring compatibility. The typical thickness of 178 µm (7 mil) and a typical filter weight of 5 mg/cm² contribute to their efficient particulate capture without excessive weight or bulk. The crucial typical water flow rate of 32 mL/min/cm² at 0.35 bar (5 psi) and typical air flow rate of 68 L/min/cm² at 0.7 bar (10 psi) highlight their ability to allow sufficient airflow for sampling without becoming a bottleneck, which is vital for accurate flow rate measurements. Furthermore, the maximum operating temperature of 260°C (500°F) means these filters can handle hot exhaust gases without compromising their integrity, a common challenge in stack emission testing. The advertised typical aerosol retention of 99.9% is the benchmark for high-efficiency filtration, ensuring that even the smallest particles are captured.
