Microseal for Thermo Scientific Injection Ports

Merlin Microseal for Thermo Scientific Users

The Merlin Microseal can be used with Thermo Trace 1300 series GCs and Thermo Trace Ultra GCs.

Thermo Trace 1300 series GCs: The Microseal fits directly in the inlet of the Trace 1300 series (with “Instant Connect” injectors) and requires only a Merlin Microseal nut (septum cap). Merlin P/N 81-12, the Thermo Trace 1300 Starter kit, includes the Microseal nut and two General Purpose Microseals. Merlin P/N 81-10 includes the Trace 1300 Microseal nut only (Microseal sold separately). These kits are compatible with both the Trace 1300 SSL and PTV inlets.

Thermo Trace Ultra SSL Inlets: An adapter kit, Merlin P/N 85-10, is required to use the Microseal with Trace Ultra SSL inlet. Note that Microseals are sold separately, none are included in this adapter kit. This kit is only compatible with SSL inlets, not PTV inlets.

Thermo Trace Ultra PTV Inlets: For PTV inlets on a Trace Ultra GC (PTV 816 RP-2004 or PTV 816), you must purchase the Thermo adapter kit, Therm PN 19050205. This kit includes all the parts necessary to adapt to either PTV inlet as well as the Trace Ultra SSL. It also includes one Microseal. Please contact your Thermo service or spare parts representative to purchase. If you would like to review a copy of Thermo’s installation manual for Thermo PN 19050205, please email
