Replacement Inlet Seals
for Thermo Scientific 1300/1310 GCs
The inlet seal at the base of the GC injection port contacts the sample and must be
changed frequently to prevent adsorption of active compounds. In addition, septum
fragments and sample residue accumulate on the disk surface, requiring disk
replacement.
Note: The 1.2 mm inlet seal is recommended when
installing two columns using a two-hole Vespel®/
graphite ferrule.

Dual Vespel® Ring Inlet Seals
Washerless, Leak-Tight Seals for Thermo 1300/1310 GCs
• Does not require a separate washer.
• Requires less torque to seal.
• Does not require retightening of reducing nut after several oven cycles.
• Extends column lifetime by preventing oxygen from reaching the column.
• Same price as the regular inlet seals with washers.
• Siltek® treatment provides enhanced inertness versus stainless steel.
Our patented dual Vespel® ring inlet seal greatly improves injection port perfor-
mance—it stays sealed, even after repeated temperature cycles, without retightening
the reducing nut! This seal features two soft Vespel® rings, one embedded in its top
surface and the other embedded in its bottom surface. These rings eliminate the need
for a washer and ensure very little torque is needed to make a leak-tight seal. The rings
will not harm the critical seal in the injector body, or any other surface, and are outside
the sample flow path.
To reduce breakdown and adsorption of active compounds, use a gold-plated or
Siltek®-treated seal.
