Markes TC-20 Multi-Tube Conditioners

Markes TC-20 Multi-tube Conditioners enhance productivity of TD–GC laboratories

Markes Multi-Tube Conditioners are compact, stand‑alone devices for the off-line simultaneous conditioning or dry-purging of up to 20 thermal desorption sorbent tubes.

Markes TC-20 conditioner is used by thermal desorption–GC analysts who want to improve their laboratory’s productivity by avoiding using valuable instrument time for conditioning sorbent tubes.

The TC-20 TAG tube conditioner is a variant of the TC-20 for those who use Markes’ RFID TubeTAG tube tagging system with single-bed sorbent tubes. It is especially useful for those working to the US EPA Method 325 regulation.

Norm Compliance: US EPA Method 325

Instrument Features

Tube Dry-Purging
Allow batches of up to 20 tubes to be simultaneously dry‑purged.
Dedicated cooling rack on the TC-20 maintains the tubes under a continuous flow of inert gas.
Improves tube throughput by allowing a second batch of 20 tubes to be conditioned while the first batch is cooling.

Benefits of Markes TC-20 Multi-Tube Conditioners

Maximum efficiency – Up to 20 sorbent tubes (3½ inch × ¼ inch o.d. as standard, or 60 mm × 6 mm o.d. with simple O-ring change) can be batch reconditioned in just 30 minutes.
Off-line sampling – Using the TC-20 or TC-20 TAG to condition 20 tubes frees up hours (and for some sorbents days), that would have been wasted by using the analytical system.
Reduced running costs – TC-20 and TC-20 TAG use nitrogen rather than expensive helium gas.
Improve analytical reliability – Dry-purging using TC-20 and TC-20 TAG removes excess water trapped during sampling, preventing it interfering with the sample analysis.
