Hofmann Electric Burner Guard

The StemAids Hofmann Electric Burner Guard is a stainless steel safety and support accessory designed for compatible Hofmann electric laboratory burners. It helps protect users from direct contact with the hot burner chimney while providing a stable grid surface for placing beakers, flasks, evaporating dishes, crucibles, and compatible laboratory vessels during flameless heating applications.

Product Description

The StemAids Hofmann Electric Burner Guard attaches directly to the burner base and works as a protective support grid above the electric burner chimney. It helps reduce the risk of accidental burns, improves vessel positioning, and supports safer handling during heating, evaporation, drying, sterilization support, and educational science demonstrations.

Made from stainless steel, the guard is durable, easy to clean, corrosion-resistant, and suitable for routine laboratory use. It is especially useful in school laboratories, college laboratories, chemistry labs, biology labs, microbiology labs, research laboratories, and training institutions where electric burners are used as gas-free alternatives to traditional Bunsen burners.
