EPDM (Ethylene Propylene Diene Monomer) septum is a type of synthetic rubber commonly used in laboratory and industrial settings. It is primarily used as a sealing material in various applications, including as a septum for sealing sample vials or containers.
EPDM septa are often used in chromatography and analytical chemistry techniques, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC). They are placed on the top of the vial or container, providing a reliable and airtight seal.
The septum allows for the injection of a needle or syringe to introduce or withdraw samples or reagents without compromising the integrity of the contents.
EPDM is favored for septa due to its excellent chemical resistance, low extractability, and ability to maintain a secure seal even under varying temperature conditions.

Rubber septa, also known as rubber stoppers or closures, are commonly used in laboratories as a sealing material for vials, bottles, and other containers. A septum (plural: septa) is a thin piece of rubber or elastomeric material that is designed to provide an airtight or liquid-tight seal when inserted into the opening of a container.
Rubber septa are typically made from a variety of elastomeric materials, such as natural rubber or synthetic polymers like silicone or butyl rubber.
These materials are chosen for their flexibility, chemical resistance, and ability to form a tight seal.

Rubber septa, also known as rubber stoppers or closures, are commonly used in laboratory settings and various industries to seal containers and provide a barrier against the outside environment.
They are made from various types of rubber, such as silicone or butyl rubber, which offer different properties and chemical resistance.
The primary purpose of rubber septa is to create an airtight seal to prevent contamination or evaporation of the contents within a container.
They are inserted into the opening of a vial, flask, or other containers and provide a secure closure.
The elasticity and flexibility of the rubber material allow for easy insertion and removal of needles or syringes while maintaining a tight seal when not in use.

20mm Crimp-top Aluminum Rubber Septa typically refers to a type of closure system used in laboratory settings. It consists of an aluminum cap combined with a rubber septa.
The aluminum cap is designed to seal the opening of a container, such as a vial or bottle, and is typically made of aluminum or aluminum alloy.
It provides a secure closure to prevent leakage, contamination, or evaporation of the contents.
The aluminum cap ensures a secure fit, while the rubber septa provide a barrier against leaks, contamination, and sample evaporation.

18mm rubber septa typically refers to a type of closure used in laboratory settings. Rubber septa are often made from materials like silicone or synthetic rubber and are designed to seal containers such as vials or bottles. They are commonly used in applications where a sample needs to be stored or analyzed under controlled conditions.Rubber septa provide an TEMPeffective barrier against air and moisture, preventing contamination and maintaining teh integrity of teh sample. They are commonly used in laboratories for applications such as gas chromatography, liquid chromatography, sample storage, or other analytical techniques.
