Beehive Shelf Porcelain, for Gas Collection

Description

The Beehive Shelf Porcelain, also known as a porcelain beehive shelf, laboratory gas collection shelf or pneumatic trough beehive support, is designed for supporting inverted gas jars or receiving tubes during gas collection experiments over water. Manufactured from porcelain, this laboratory accessory provides a stable support for compatible gas collection vessels placed inside a water-filled pneumatic trough. Its design allows gas produced during a chemical reaction to be directed into an inverted collecting vessel.

The range includes two available diameters: 75 mm and 100 mm, allowing laboratories to select an appropriate shelf according to the dimensions of their pneumatic trough and receiving jar. The 75 mm Porcelain Beehive Shelf provides a compact supporting arrangement for smaller gas collection setups. It is suitable for routine chemistry demonstrations using appropriately sized gas jars and pneumatic troughs. The 100 mm Porcelain Beehive Shelf offers a larger supporting diameter for compatible receiving vessels and laboratory gas collection arrangements.

The beehive shelf is used with a gas delivery tube connected to a suitable gas-generating apparatus. In a typical arrangement, the delivery tube passes through the shelf’s side opening, allowing gas to rise through the upper opening into an inverted receiving vessel. During collection, the incoming gas displaces water from the receiving jar, gradually filling the vessel. This method is suitable for gases with sufficiently low water solubility and that do not react significantly with water under the experimental conditions. These porcelain beehive shelves are commonly used in school chemistry experiments, gas preparation demonstrations and introductory laboratory investigations involving the collection and observation of gases.

The appropriate size should be selected according to the receiving vessel, trough dimensions and laboratory setup. Ensure the collecting vessel is stable and that the gas delivery pathway remains unobstructed. Safety Precautions: Handle porcelain carefully to prevent cracks or breakage. Use appropriate protective equipment and ensure adequate ventilation when preparing or collecting gases. Follow approved laboratory procedures, particularly when working with flammable or hazardous gases.

Each selected variation is supplied as one Porcelain Beehive Shelf in the chosen 75 mm or 100 mm diameter. Pneumatic troughs, gas jars, delivery tubes and other gas collection accessories are not included unless specified separately.
