Description

Cytivas 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
