A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.

Aug 20, 2021 · Generally, “septa” is a bi-layer of silicone and polytetrafluoroethylene (PTFE). Septum, inserts, and vial caps are widely used in order to achieve leakage prevention as well as to avoid

Bottle Septa. Septa for bottles provide an airtight seal for bottles that prevents environmental contaminants but allows for the removal of the bottle’s contents by piercing with sharp needles. Septa bottle caps are generally available for open-top and screw caps and allow for aseptic syringe dispensing, as well as the addition of materials.

Rubber septum consists of a disk of rubber or similar material used to seal a vial or other device. It is installed along the inside of a cap, which is typically made of metal or plastic. A syringe needle pierces the rubber septum for the purpose of injection and, on withdrawal, the elasticity of the septum ensures that the hole reseals.

PTFE/Silicone/PTFE septum is recommended for the most critical applications such as ultra trace analysis or where there is a longer time between injections or for internal standard methods. PTFE/Silicone/PTFE septa provide superior performance with Aijiren 1050, 1090, , or

For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.

Our certified caps and septa are designed and fabricated for proper sealing and trouble-free operation with Aijiren instruments. We also perform chromatographic tests on silicone septa to ensure the highest standards of purity, and to eliminate outliers and sample errors.
