operating temperature range for this septum is from –20 to 125°C. Black Rubber Septa: (C4020-40) Black rubber septa are molded from a higher density rubber compound compared to the standard red rubber. This septum has characteristics similar to the gray butyl stopper with a slightly smaller temperature range of –20 t0 100°C. The
Products. Septa. By definition, a 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
Ace Glass. Specially engineered to fit standard taper joints and tubes. Manufactured under white room conditions for extreme cleanliness. Made of a more dense rubber, low extractables and a better fit (50% to 80% on joints) these septa are much less likely to fail in the presence of solvents. Compare this item.
Silicone rubber is a high-performance elastomer with an unusual combination of properties. These properties range from high-temperature performance, durability, electrical insulation as well as transparency. These features make silicone rubber a high-performance material in several sectors. Find out how to meet the demanding performance

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 are always best. What force is required to penetrate the septum? Generally, silicone septa are more easily pierced than red rubber or butyl septa. For thicker, hard-to-pierce septa, a small gauge (23 gauge) needle may be required, or a stronger S-needle can be used. Preslit septa are the best option for
Jun 1, 2021 · 1. Introduction. Silicone rubber is a synthetic polymer consisting of silicone-oxygen backbones, which give unique material properties. These material properties include biocompatibility, superior temperature and chemical resistance, and good mechanical and electrical properties [ 1, 2 ]. Due to its material properties, silicone rubber has a
The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.
