Markes’ industry-standard-size TD tubes (3½″ × ¼″ o.d.) are available in three materials: stainless steel, inert-coated stainless steel and glass. They are permanently labelled with a unique serial number, barcode and sampling flow arrow for easier use and tracking.
Markes’ thermal desorption tubes are strictly quality controlled – packed to a tolerance of ±2.5% by weight, or better. The range comprises method-compliant, application-specific and general-use sorbent tubes, to simplify method development. The tubes are supplied either conditioned and capped for immediate use or unconditioned.
