Narrow-mouth septa bottles are available in clear or amber Type III glass equipped with a 0.045 in. thick blue PTFE/silicone septa in an open-top 24-414 polypropylene cap. The I-CHEM molded-in septa retainer ring holds the septa securely in place without bonding to the cap, so septa can be removed.
An Aijiren Septum is Not Just a Septum White Paper The septum is one of the three main components of your sample containment system, consisting of the vial, septum, and cap. The septum is highlighted in red in Figure 1. Autosampler needle Septum Cap Vial Sample location Figure 1. A basic illustration of an Aijiren sample vial, highlighting the
Aijiren Technologies. Septa are the preferred septum for autosamplers and are ideal for overnight runs. You can make up to 400 injections per septum and its soft 45 Durometer rating is easy on autosampler needles. Advanced green Septa are long-life, high temperature devices. Aijiren offers users a high-performance.

PTFE coating ensures compatibility. Natural rubber/Ethylene Tetrafluoroethylene (TEF): features excellent resealing properties. Silicone/PTFE: cleanest solution for contaminant free sample handling; autoclavable, too. PTFE/Silicone/PTFE: PTFE laminated to both sides of high-purity silicone to prevent coring.
PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.
Jan 2, 2006 When the needle pierces the septum, the rubber is exposed to the sample by either headspace or direct contact, which will affect the quality Silicone Septum at Thomas Scientific. High-quality borosilicate glass and rigid, autoclavable cap Standard open top, flat silicone/ PTFE septum design 40 mL capacity Available in clear or ...

dimple in the center of each septum to guide the syringe needle into the inlet. With the dimpled CenterGuide, the syringe needle enters the septum at precisely the same spot each time. Because bleed from septa can be a major contributor to the overall signal, a high-quality septum is an absolute necessity for analyses demanding increased
PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.
