General Laboratory. General labware; pre-slit silicone/PTFE septa: 10 x 100: 139,04 ... LABORATORY CONSUMABLES, INSTRUMENTS AND reagents.
Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.
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.
a barrier (usually PTFE) and one to allow for resealing (usually silicone) • Tri-layer (also known as a sandwich septum): Still made from two distinct materials – usually silicone surrounded on both sides by PTFE Table 1. Septa chemical compatibility. PTFE/Silicone/PTFE* PTFE/Red rubber Fluoroelas tomer PTFE/Butyl
These septa provide adequate venting in order to prevent vacuum formation in the sample vial, which allows for superior sample draw reproducibility across vials. Pre-slit PTFE/Silicone septa have a working temperature range from -40 degrees C to 200 degrees C. The chemical compatibility of the septum is that of silicone, but it does not have
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.
Bottle Caps. Bottle caps provide an air-tight seal that ensures that a bottle’s contents are leak- and spill-proof, resistant to temperature and that the bottle can be moved. The most ubiquitous style is the threaded screw cap. Caps are available in different sizes and colors and can be specialized for the type of container they sit upon.
Stoppers, also known as bungs, are used to give an airtight seal to laboratory flasks and test tubes by fitting tightly inside the neck of the container and preventing material from spilling. Stoppers can be made of glass, cork, rubber, or silicone. They are typically designed with a conical shape, but straight, flanged, and tapered options are
It is equipped with a polypropylene cover with an open top and a PTFE/silicone low leakage gasket bonded to the cover. The level 1 vials have been assembled and quality checked before they leave the factory. 40ml Glass TOC Vials with White Polypropylene Hole Cap, PTFE/Silicone Septa and Opaque HDPE Dust Cover.

Deactivated Clear Glass 12 x 32 mm Screw Neck Vial with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk. When working with highly polar analytes that may associate with the polar glass surface, chromatographers choose deactivated vials as the effective vial of choice. These glass vials are treated with gas-phase, reactive organosilane
Content. Aijiren produces matching Closures for HPLC Vials, especially Septa, which is made of Silicone and PTFE. Septa can ensure that the hplc vials are sealed. At the same time, it must ensure that the automatic injection needle can penetrate into the interior of Vias for sampling, so for Septa There are certain requirements for the thickness.
Aijiren's headspace vial caps are engineered to prevent sample contamination while providing consistent, secure seals. Headspace vial caps are available in a variety of materials including aluminum, bimetal, and steel; headspace vial cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature varieties.
Headspace Silicone Convenience Kit contains everything you need to run Gas Chromatography. Each product is manufactured using strict quality control standards resulting in consistent cap dimensions with septa which may be certified for higher purity grades.
