VOCs Combined Sampling Tube Stainless Steel with Copper Cap ¼” × 3½”
Specifications
The VOCs Combined Sampling Tube (Stainless Steel with Copper Cap, ¼” × 3½”) is a precision-engineered thermal desorption sorbent tube designed for the reliable collection and analysis of volatile organic compounds (VOCs) in air and gas samples. Manufactured from high-grade stainless steel and sealed with durable brass/copper storage caps, this industry-standard sampling tube delivers exceptional performance in environmental monitoring, industrial hygiene, and indoor air quality testing applications.
This ¼-inch outer diameter × 3½-inch length (6.35 mm × 89 mm) tube conforms to the internationally recognized “industry standard” format, ensuring seamless compatibility with leading thermal desorption systems including PerkinElmer, Markes International, Dani, Shimadzu, and major domestic thermal desorbers. Available in multiple sorbent configurations—including single-bed, dual-bed, and triple-bed combinations—our VOCs sampling tubes are engineered to meet the rigorous demands of regulatory methods such as HJ734-2014, EPA TO-17, and EN ISO 16017.
