Sample Tubes with Treated Sorbents

  • SKC Sample Tubes with Treated SorbentsConvenient — Ready for use

  • Low backgrounds

  • Widest variety of treated sorbents available

SKC offers a complete line of sample tubes with sorbents that have been washed, coated, or treated in a special way to better collect specific chemical hazards. For many airborne chemicals, these sorbents provide a suitable sampling alternative to wet chemistry methods using impingers. SKC provides treated sorbent sample tubes to meet published NIOSH and OSHA methods along with methods published by leading researchers.

The glass tubes are flame-sealed to ensure sorbent purity and are ready for immediate use. SKC uses extensive cleaning processes and quality control measures throughout the manufacturing process to eliminate background.
