Hofmann Electric Burner

The StemAids Hofmann Electric Burner is a flameless laboratory heating device designed as a safe and efficient alternative to traditional gas Bunsen burners. It provides a strong hot-air heating stream for laboratory heating, evaporation, drying, sterilization support, combustion demonstrations, and routine educational science practicals.

Product Description

The StemAids Hofmann Electric Burner is suitable for laboratories where open flame, gas pipelines, or gas cartridges are not preferred. It uses electric hot-air heating through a ceramic chimney, allowing users to heat test tubes, crucibles, small beakers, flasks, dishes, and compatible laboratory vessels without using natural gas, butane, or propane.

The enclosed heating design makes the burner less sensitive to accidental liquid overflow compared with open coil or gas-flame systems. Its heat-resistant ceramic stack and compact bench-top construction make it suitable for school laboratories, college laboratories, chemistry labs, biology labs, microbiology labs, research laboratories, and institutional training environments.

How to Use

1. Place the StemAids Hofmann Electric Burner on a clean, dry, stable, level, and heat-resistant laboratory bench.
2. Ensure the surrounding area is free from paper, solvents, plastic items, loose clothing, and flammable materials.
3. Check the power cord, plug, ceramic chimney, housing, and heating area before operation.
4. Connect the burner to a suitable 230 V / 50 Hz power supply with proper electrical safety protection.
5. Switch on the burner and allow the ceramic chimney to heat until the required hot-air stream is produced.
6. Use suitable holders, tongs, clamps, or heat-resistant tools to position test tubes, crucibles, dishes, or small vessels above the hot-air stream.
7. For controlled heating, use a compatible power regulator if required by the laboratory procedure.
8. Monitor the sample, vessel, and heating process throughout the experiment.
9. After completion, switch off the burner and disconnect the power if required by laboratory practice.
10. Allow the burner to cool completely before cleaning, moving, or storing.
