A turnover flange septa is a type of seal used in laboratory glassware, such as flasks or bottles, to prevent leaks and contamination. It consists of a flat disc-shaped piece of rubber or silicone material with a centre hole, which is placed over the opening of the glassware, and a flange or lip around the perimeter of the disc.
Turnover flange septa are available in different materials, sizes, and thicknesses, depending on the specific application and the type of glassware being used. They can be sterilized for use in sterile environments and are easily replaceable when they become worn or damaged.
