Top-quality Sorbent Tubes and Accessories for Thermal Desorption
13 Jul 2017Quality of tubes varies hugely between manufacturers, and should be the first thing to consider when purchasing, because it ultimately affects the quality of your data.
Markes has been making sorbent tubes for 20 years. To ensure perfect results, each tube is individually packed under strict quality-control processes, and then flow-tested before leaving our factory.
What’s more, tubes can be preconditioned, meaning you could benefit from artefact levels much lower than those from other manufacturers.
The Markes advantage
- Tubes available in high-quality stainless steel, inert-coated or glass.
- 3½-inch tubes compatible with instruments from all major TD manufacturers.
- Innovative tube-tracking features.
- Application-optimised or customised packing to extend the analyte range monitored.

Further labelling options for tube tracking – includes laser-etching, banding and RFID-tagging (TubeTAG™). Diffusion-locking SafeLok™ options for additional peace of mind. Stringent quality control – our tubes are packed to a tolerance of ±2.5% or better. Application-specific sorbent tubes – optimally packed for applications ranging from air toxics to material emssions testing. Our sorbent tubes can also be ordered conditioned and capped, so that they’re ready for use on arrival. All our sorbent tubes can be supplied: empty for you to pack yourself (or for direct desorption); pre-packed with one sorbent bed for diffusive (passive) monitoring applications; or pre-packed with up to three sorbent beds for pumped (active) monitoring applications. We also supply 4½-inch DAAMS tubes (regular and high-flow, in any of the above materials) – contact us for details.
