The Pallflex Emfab Filters, Pall Life Sciences 7219, Pack of 100 are engineered with precision for critical air sampling. The core material is pure borosilicate glass microfibers, providing an excellent matrix for capturing fine particulates. This is reinforced with a woven glass cloth, adding significant structural integrity without compromising airflow. The entire composite is then bonded with PTFE (Polytetrafluoroethylene), a material known for its chemical inertness and non-stick properties, ensuring no interference with the sample.

The filters boast a 25mm diameter, a standard size that ensures compatibility with a wide range of sampling equipment. Their typical thickness is 178 µm (7 mil), a balance that allows for substantial particulate loading while maintaining good airflow. The typical filter weight is 5 mg/cm², providing a consistent baseline for gravimetric analysis. Crucially, these filters exhibit low air resistance, with a typical water flow rate of 32 mL/min/cm² at 0.35 bar (5 psi) and a typical air flow rate of 68 L/min/cm² at 0.7 bar (10 psi). This efficiency is vital for accurate sampling, especially in high-flow or high-resistance applications. Furthermore, they are designed to withstand temperatures up to 260°C (500°F), making them suitable for sampling hot exhaust streams. Their typical aerosol retention is an exceptional 99.9%, underscoring their high-efficiency filtration capabilities.

These specifications are not just technical jargon; they translate directly into real-world performance. The borosilicate glass microfibers offer excellent chemical resistance and thermal stability, crucial when sampling harsh environments. The woven glass cloth reinforcement ensures that the filter doesn’t distort or tear under pressure, maintaining its shape and effective filtration area. The PTFE bonding prevents any potential leaching of filter components into the sample, guaranteeing sample purity. The low air resistance is paramount for accurate flow rate control in sampling systems, preventing backpressure and ensuring consistent sample volumes. The high aerosol retention means that even the smallest, most critical particles are captured reliably, providing accurate data for environmental and health assessments.
