Beehive Shelve (Porcelain) is a laboratory support accessory used primarily in gas collection experiments involving pneumatic troughs. It serves as a platform to hold gas jars or other collection vessels while allowing gases to pass through the central hole from a delivery tube during chemical reactions. Manufactured from high-grade porcelain, the beehive shelve offers excellent heat resistance, chemical stability, and mechanical strength. Its smooth glazed finish ensures durability, easy cleaning, and protection against acids and alkalis commonly used in laboratory environments.
