Tube replacement

Discount on new sorbent tubes when we replace your used tubes

Used sorbent tubes can now be returned to Markes to claim a discount on new tubes.

This applies to industry standard tubes: stainless steel, inert stainless steel and glass. 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 such as:

• Camsco
• Perkin Elmer
• Supelco / Sigma-Aldrich
• SKC
