A receiver adapter, straight, is a type of laboratory glassware accessory used to connect a receiver flask to a condenser or other glassware component. It consists of a straight tube with a socket at one end that fits onto the neck of the receiver flask and a cone at the other end that fits into the joint of the condenser or other component.

The straight design of the adapter allows for a simple and direct connection between the glassware components. The receiver adapter, straight, 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 adapter ensures a tight seal between the glassware components, minimizing the risk of leakage or contamination during the experiment. The straight design of the adapter also allows for a more straightforward and straightforward setup, making it easier to access and manipulate the components.
