Description

A beehive shelf is a circular, dome-shaped laboratory support accessory typically made of glazed white porcelain or ceramic. Designed for use in a pneumatic trough, it features a flat circular top with a central hole and a notched opening on its side to allow a delivery tube to pass through. This structure provides a stable platform for supporting a gas jar or collection vessel while allowing gas to be bubbled upward and collected via the displacement of water. Its robust, chemical-resistant construction ensures durability during various chemistry experiments involving gas evolution.
