Cytiva Whatman PM2.5 Air Monitoring Membrane Filters
Description
• Cytiva's Whatman PM2.5 PTFE membrane filtration devices are designed for PM2.5 ambient air testing during continuous monitoring
• These high-purity, thin PTFE membrane filters are sequentially numbered and come with chemically resistant polypropylene support rings
• PTFE membrane filters offer high chemical resistance and mechanical strength
• One of the major applications for the PTFE membranes is the clarification of corrosives, solvents, and aggressive fluids
• This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column
• Air and gas sterilization make use of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols
• Polypropylene (PTFE) support rings for robotic air sampling and monitoring
• Thermally stable design eliminates curling, keeps the membrane material flat, and makes the filter robot-friendly
• Sequentially numbered filtration devices
• Low tare mass for accurate gravimetric analysis and determinations
Specifications:
• Alkalinity max.: 25 µeq/g of filter (Test Method: Section 2.12 EPA/600/R-94/038b)
• Material Polytetrafluoroethylene (PTFE)
• Particle Retention (0.3 mu m) Min.: 99.7% - Test Method: ASTM D 2986-95a
• Pore Size: 2 µm
• Support Ring: Yes
• Support Ring Material: Polypropylene (PP)
• Support Ring Width: 3.68 mm +/- 0.00 to 0.51 (Test Method: template)
• Total Support Ring Thickness: 0.38 mm +/- 0.04
