Ideal for sampling airborne metals, silica, and dust.

• Polyvinyl chloride
• Resistant to acids and alkalis
• For gravimetric analysis

Polyvinyl chloride (PVC) membranes resist acids and alkalis. Low ash content, moisture pick-up, and tare weight make membranes well suited for gravimetric analysis of airborne particulates. Pore size: 5 µm. Filter 28139-743 includes support pads.
