High Volume Polyurethane Foam (PUF) Tubes
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.
