Polyurethane PUF tubeHigh Volume PUF Tube

Polyurethane Foam (PUF) tubes are available in low volume or high volume versions.




The low volume PUF tubes (22 x 100 mm) are for measurements up to 24 hours at flow rates between 1 to 5 L/min. They meet the specifications of EPA TO-10A, EPA-IP-8, ASTM D4861, ASTM D4947.

The high volume PUF tubes (65 x 125 mm) are designed for use with high volume samplers for ambient air sampling of organochlorine pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). The PUF-only sorbent tubes meet ASTM D6209 and EPA IP-7, TO-4A, TO-9A and TO-13A, and are packed with precleaned PUF for low background. The PUF/XAD-2 combination tube meets EPA Method 600/8-80-038 specifications, and contains cleaned XAD-2 sorbent between two PUFs, which improves volatile component extraction during analysis.

To select a tube for a specific compound refer to the SKC Sampling Guides or use the SKC online Hazard Database
