Sorbent tube customisation and replacement

Discount on new sorbent tubes when we recycle your used tubes

Used sorbent tubes can be returned for a discount on new tubes, (stainless steel and inert stainless steel). We would ask that returns documentation be completed and approved before tubes are returned to Markes (with tubes subject to a risk assessment). Glass tubes, DAAMS tubes and any tubes that may have been in contact with dangerous substances are not returnable.

We also accept thermal desorption sorbent tubes from non-Markes manufacturers, provided the shipping/documentation criteria are met.

When should you replace a sorbent tube? Read our blog to learn more.

Tube customisation options

  • Up to 10 alphanumerical characters, to indicate sorbent type, maximum conditioning temperature, project name, purchase date, company name etc.
  • Up to five permanent black bands, as a visual indicator of the number of sorbent beds or to denote particular sampling campaigns
  • Company names or logos

Markes’ sorbent tubes are available in a variety of materials, sorbent packing combinations and with a wide range of labelling options. All Markes’ tubes feature sophisticated labelling with a unique ID number in clear barcode and numerical format, plus a sampling flow arrow. Tubes can also be customised to align with end-user and analyst workflow.

Our Tube configurator willl help with selecting the right sorbent tube for the vast majority of popular applications.
