SafeLok Sorbent Tubes

• Feature patented diffusion-locking technology at either end of the sorbent bed to prevent diffusive ingress of atmospheric contaminants outside the pumped sampling period.
• Significantly reduce the risk of contamination from poorly fitted or loose caps.
• Prevent necking and other damage to the ends of tubes caused by over tightening of the tube seals.
• Stop the ingress of volatiles from the laboratory air during routine capping and uncapping procedures.
• Facilitate pumped sampling over extended periods at low (<1 ml min) flow rates allowing the collection of time weighted average concentration data over periods of weeks or months without exceeding safe sampling volumes.>
• Individually etched with unique serial number for convenient sample identification.
• Robust barcode—the most reliable “code 128” format—on tube for recording and tracking.
• Available unconditioned or preconditioned and ready to sample. Tubes are reusable after thermal desorption for most applications.
