Inert steel tubes - SafeLok

SafeLok™ tubes with diffusion-locking SafeLok options give additional peace of mind, or for sampling at low flow rates.

Inert-coated tubes are a robust alternative to glass tubes for sampling thermally labile and reactive compounds. Markes is an approved partner of SilcoTek, who treat the entire surface of the tubes with their industry-leading SilcoNert™ coating. This eliminates surface adsorption of active compounds and avoids the breakdown of thermally labile analytes during analysis.
