Tube replacement

Discount on new sorbent tubes when we recycle your used tubes

Used sorbent tubes can be returned for a discount on new tube purchases, (stainless steel and inert stainless steel). Returns documentation must 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.
