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
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.
