Thermal Desorption Unit (TDU) Tubes (Unconditioned and Conditioned & Capped), Restek

High-quality thermal desorption tubes are suitable for ppt to ppm concentrations of volatile organic compounds (VOCs) in ambient, indoor, personal, and industrial hygiene environments.

• Variety of sorbents to collect a wide range of VOCs
• Use corrosion-resistant glass tubes for excellent inertness
• Allow monitoring of sorbent bed condition
• Choose stainless steel tubes for greater durability in the field
• No sampling pump necessary for passive sampling with diffusion caps
• Individually etched with unique serial number for convenient sample identification
• The most reliable barcode "code 128" format on tube for recording and tracking
• Each tube has an arrow indicating flow direction to reduce errors during use
• Available unconditioned or preconditioned and ready to sample
• Tubes are reusable after thermal desorption for most applications
