Sample Tubes with Treated Sorbents
 Convenient—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.
