Black Rubber septum is an economical choice for applications where reduced levels of vapor penetration are desired. Black rubber septa should be used with sturdier injection needles. PTFE Aluminum Foil (High Temperature Septum - C4020-37) Aluminum backing on this septum provides an effective vapor barrier along with high temperature compatibility.
The flange suspends the insert correctly centered in the vial without causing a bulge in the septum when the cap is screwed on. Limited volume inserts are an economical solution when there is a limited amount of sample and injection is done using an autosampler.
