Precleaned and Ready to Use
SKC Low-volume PUF Tubes are precleaned to meet or exceed method specifications for purity and are packaged to allow immediate use without further treatment. SKC PUF tubes are also reusable. See custom PUF and repack information.

PUF/Tenax® Multi-bed Tube for Pesticides and PCBs
ASTM Method D4861 and EPA Methods TO-10A and IP-8
Packed with two 30-mm sections of polyurethane foam (PUF) and one 750-mg section of Tenax, this tube is suitable for non-occupational exposure monitoring of homes, public buildings, and office buildings. It can simultaneously collect many of the airborne chemicals that can contribute to "Sick Building Syndrome" as described in ASTM (American Society of Testing Materials) D4861.
Cat. No. 226-124


PUF Tube for Pesticides
EPA Methods TO-10A and IP-8 and ASTM Methods D4861 and D4947
Designed for sampling common pesticides including organochlorine, organophosphorus, pyrethrin, triazine, carbamate, and urea, this tube contains a single 76-mm PUF plug.
Cat. No. 226-92


PUF/XAD-2® Multi-bed Tube for Pesticides
This tube contains two 30-mm sections of PUF and one 1500-mg section of XAD-2 sorbent.
Cat. No. 226-143


PUF Tube with Pre-filter for Dioxins
This PUF-only tube contains a glass fiber pre-filter followed by a single 76-mm PUF plug.
Cat. No. 226-126

#	Use this PUF/Tenax sorbent combination tube for sampling compounds with high vapor pressure. It also allows the simultaneous measurement of many airborne chemicals that can contribute to Sick Building Syndrome (SBS).
†	See the SKC EPA Air Sampling Guide for a complete list of specific compounds for each method.
Note:	PUF tubes used in the Statements of Work for Superfund sites must be used and analyzed within 14 days of being cleaned.
Note:	EPA methods allow some flexibility accommodating similar sampling protocols, however, such flexibility places documentation responsibility on the user. For a detailed explanation, refer to the methods.
