Multiple adapters, two necks, angled is a type of laboratory glassware accessory used to connect two pieces of glassware with angled joints to a single joint. It consists of two angled sockets or cones, arranged at an angle to each other, that fit onto or into the angled joints of the glassware components.

The multiple adapters allow two glassware components to be connected to a single joint, allowing for versatility and flexibility in laboratory setups. This type of adapter is commonly used in chemical experiments, especially in the areas of distillation and reflux, where it is important to have a secure and leak-proof connection.

The multiple adapters ensure a tight seal between the glassware components, minimizing the risk of leakage or contamination during the experiment. The angled design of the multiple adapters allows for the integration of two glassware components into a single setup, making it a useful tool for laboratory professionals.
