The silicone elastomer layer is dense but still easily pierced by most headspace sampling needles. 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. The Black Rubber septum is an
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.
Medical grade silicone rubber is the material of choice for many medical and bioscience applications. It is biochemically inert, elastic and flexible, naturally resists bacterial growth, can be formulated to be anti-microbial, is heat stable and autoclavable. Silicone rubber parts can be easily sterilized, whether by Ethylene Oxide gas, gamma
Septa can be made from a range of materials including PTFE, silicone, red rubber, luoroelastomers, and butyl to name. few. The materials are layered together in one of three options: Choose a material that is as inert as possible to your sample analyte and makeup solvents.
May 7, 2022 · Silicone processing methods are a series of widely used manufacturing processes which transform silicone rubbers to create a final product with specific characteristics: shape, hardness or elasticity, color, degree of transparency, tear strength, resistance to environmental or mechanical stress, etc.
Aug 15, 2022 · A silicone (or polysiloxane) is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, cooking utensils, adhesives, lubricants, medicine, and thermal and electrical insulation. Some common forms include silicone oil, grease
Ideal for use with open-top caps to access container contents with a syringe.Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure
The silicone elastomer layer is dense but still easily pierced by most headspace sampling needles. Black rubber septa 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. The Black rubber septum is an economical choice for
The NR Series of Natural Rubber liners and septa are designed for high performance and economy. Manufactured from a high quality custom developed compound (5652), these Natural Rubber products exhibit good re-sealability, very good chemical resistance and can withstand temperatures up to 100 o C. Natural Rubber septa work particularly well with organic solvents and are most commonly supplied
Rubber septum design varies widely depending on the application. Medicinal vial septa are typically compression molded out of Silicone or Butyl rubber in multi-cavity molds within a high controlled manufacturing environment. Other septum types may include a chemical barrier layer, most commonly PTFE, or in extreme case, two barrier layers.
Jun 8, 2023 · The Challenges with Traditional Processes The manual nature of traditional silicone rubber manufacturing processes brought a host of challenges. For one, it was time-consuming and labor-intensive, which limited the scalability of production.
Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that
Jan 14, 2022 · In the present article, Nambiathodi, Varghese and Varghese prepared and studied combinations of natural rubber, butadiene rubber and latex reclaim to develop cost-efficient tread materials. Rajapaksha, Perera and Vidanapathurana have shown that natural rubber can be used to store energy to replace commercially available toxic polymers.
