Rubber tubing is a flexible and durable type of tubing commonly used in laboratories for transferring liquids or gases between containers or instruments. High-pressure rubber tubing is designed to withstand higher pressure than regular rubber tubing and is often used in applications that require the transfer of liquids or gases under high pressure, such as in gas chromatography, HPLC or liquid chromatography systems.

High-pressure rubber tubing is made from high-quality synthetic rubber, reinforced with layers of braided or spiraled steel wire or fiber to increase its strength and durability. The tubing is available in various diameters and thicknesses to fit different instruments and is often color-coded for easy identification.

High-pressure rubber tubing is preferred over other types of tubing materials, such as PVC or rubber, because it is less reactive and does not leach harmful chemicals or odor into the fluids being transported. It is also easy to clean and sterilize, making it a versatile and convenient tool for laboratory work. Additionally, the reinforcement layers provide the tubing with a high level of resistance to pressure, abrasion, and tearing, making it suitable for use in demanding applications.
