elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/Silicone Septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is

Chemglass. Replacement septa for use with MW-102 open-top screw caps on Minum-Ware® glassware components. Septa are made of silicone rubber with one side having a RED PTFE face, while the opposite side has an ultrathin covering of polypropylene to prevent needle coring when penetrating septa. Compare this item.
The clear borosilicate glass vial is shock and temperature resistant The closure is a 1 piece PTFE/Silicone speta bonded to the PP open hole cap Vial is designed for volital organic analysis Certified for EPA Sampling. 40ml Clear Vial found in: 40mL Clear Vial, 40ml clear septa vial w/0.25mL 1:1 HCL, 40ml vial, clear borosilicate glass, 24-414
Jul 10, 2012 · Moreover, Septum D performance is generally superior to the other septa. Septum C bleeds even at 100°C, suggesting its unsuitability in routine high-temperature GC–MS studies. Significantly, all septa used in this study bleed phthalate compounds at much lower IP temperature, contrary to the respective manufacturers’ claims on quality and
Aug 5, 2022 · For best performance the septa should be inert, low off-gassing of silicone oligomers, soft enough to avoid bending the needle and reseal after injection, and resistant to coring by the syringe. 1
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 of the data in various ways. This application note discusses the influences of pierced PTFE/silicone septa in GC-MS experiments. Two examples are given: the loss of nonpolar volatile organic compounds
-40 °C -40 °C -60 °C natural rubber/TEF natural rubber/TEF; butyl/PTFE red rubber/ PTFE silicone/ PTFE Thin, fragile needle? Soft and thin septa required e.g. silicone/ PTFE Blunt, thick needle? Slit/pre- cut liner as penetration aid (HPLC) silicone/ PTFE, slit Critical analysis? Very clean liner required
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.

High quality silicone, resists coring and tearing reducing the risk or mat particulate entering the well. Well perforations will seal themselves, after penetration, ensuring an airtight closure. Made of research-grade silicone, they can be autoclaved, and following a 10% bleach wash and ethanol rinse protocol may be reused.
Jul 24, 2019 · Here are some options for cleaning: Rubbing Alcohol: This is one of the easiest and most common methods of sterilizing medical grade silicone. This will kill off any bacteria that may be present, as well as dust or particles. Autoclave: An autoclave uses steam to sterilize platinum-cured LSR, which can destroy microorganisms.
