Cytiva's Whatman PM2.5 PTFE membrane filters are designed for PM 2.5 ambient air monitoring. These high-purity, thin filters are sequentially numbered and come with chemically resistant polypropylene support rings.

• Polypropylene support rings for robotic air sampling
• Thermally stable design eliminates curling, keeps the membrane flat, and makes the filter robot-friendly
• Sequentially numbered filters
• Low tare mass for accurate gravimetric determinations

Produkowany w sterylnych warunkach. Te odporne chemicznie filtry, z niskim podkładem chemicznym, pozwalają na wrażliwe, niezakłócone oznaczenia. Wolne od klejów i spoiwa.

Continuous air monitoring methods require a chemically resistant air sampling filter material that can withstand environmental pollution potentially containing a variety of contaminants and can still deliver accurate results.

PM2.5 PTFE membrane filters from Cytiva business also feature a thermally stable design, making them ideal for ambient air monitoring. These membranes come in a polypropylene support designed for use in robotic air sampling of ambient air pollution.
