Polyurethane Foam (PUF) Tubes
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.
- 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).
To select a tube for a specific compound refer to the SKC Sampling Guides or use the SKC online Hazard Database
The Low Volume PUF Tubes:
- Meet the specifications of EPA TO-10A, EPA-IP-8, ASTM D4861.
- Can be used with personal sample pumps up to 5L/min
- Precleaned to meet method specifications
- Suitable for ambient, indoor or personal air sampling
- Sample up to 24 hours

The PUF-only sorbent tubes meet ASTM D6209 and EPA IP-7, TO-4A 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.
