Caps are compatible with all industry-standard sorbent tubes: (6.35 mm o.d.) and 6 mm o.d. tubes (including DAAMS and TD Mini-tubes).
For storage, two caps are required per tube. For passive sampling, one cap is required for the non-sampling end, while a diffusive sampling cap is used on the sampling end.
Long-term (brass) storage caps ship as standard with tubes purchased pre-conditioned from Markes. Ferrules should be replaced routinely or when switching applications. To prevent overtightening of long-term storage caps, Markes recommends the CapLok tool.
Storage caps - short-term
Short-term storage caps are convenient for in-lab use and when using Markes’ patented SafeLok technology. They are ideal for sorbent tubes being analysed almost immediately after sampling (up to 3 days), and for inexperienced users. For transport or storage for more than 3 days, long-term storage caps must be used.
Markes International’s SafeLok tubes have a diffusion-locking insert at each end, to ensure sample integrity throughout storage, transport and analysis. They complement short-term storage caps and make them ideal for use by inexperienced users, adding an additional level of sample security and minimising risk of tube/cap damage.
Caps are compatible with all industry-standard sorbent tubes: (6.35 mm o.d.).
