Spirit Burner

The Spirit Burner (Article# LS11-320) is a stainless-steel alcohol lamp with a flat circular base body, a central cotton wick mounted through a threaded porcelain wick holder, and a domed extinguisher cap secured to the body by a metal chain. The ratcheted knob alongside the wick holder adjusts the cotton wick height to control flame size without direct contact with the burning end. The stainless-steel body holds approximately 150 mL of alcohol fuel and sits on a wide stable base that prevents tipping during bench-side use. The chain-attached cap allows instant flame extinction without risk of cap misplacement.

The spirit burner fuel reservoir uses denatured alcohol or isopropyl alcohol, which burns at a controlled temperature — lower than a Bunsen burner — producing a clean, steady flame suited to instrument sterilization and dental laboratory heating tasks. The domed extinguisher cap cuts off oxygen supply instantly when placed over the wick, extinguishing the flame without blowing and preventing alcohol vapor escape during storage. The stainless-steel construction resists corrosion through repeated alcohol exposure and withstands bench surface heat without deformation.

Dental professionals, laboratory technicians, and clinicians use the Spirit Burner for quick sterilization of small metal instruments between patient procedures, heating wax spatulas, tempering impression compound, and annealing gold foil. The spirit burner stove configuration — with its wide base and controlled wick — keeps the working flame stable during fine dental laboratory tasks where a Bunsen burner would deliver excessive heat output for the application.

Leader Surgical backs every instrument it produces with the same manufacturing discipline — consistent material quality, verified construction, and dimensional accuracy that clinicians can count on tray after tray.

What is the difference between a spirit burner and a Bunsen burner?
A spirit lamp is a candle that is lit with alcoholic fuel. A Bunsen Burner is a piece of equipment used in laboratories that is designed to burn a gas fuel in a single flame to provide heat with little light pollution. With a reservoir holding liquid fuel a Spirit Lamp may be adjusted to burn just the vapor.
