Spirit Lamp

Spirit Lamps — Glass, Stainless-Steel and Flame-Control Alcohol Burners for the Dental Bench

A spirit lamp — sometimes called an alcohol lamp — is the simplest heat source on a dental bench: a spirit-filled reservoir, a cotton wick, and a cap to snuff and seal it. Lit, it throws a steady, near-smokeless flame hot enough to warm a wax knife, soften modelling wax, or take the chill off a gutta-percha cone before condensation, yet it is small enough to sit beside the other hand instruments without a gas line or a power point. It is cheap, portable, and ready the moment a match is struck.

Types of spirit lamps

Glass-bowl spirit lamps

A clear glass reservoir lets you read the spirit level at a glance and top up before the wick runs dry, which is why it tends to be the pick for a teaching lab or a bench several people share. The Samit Spirit Lamp Glass is a plain glass model of this kind.

Stainless-steel spirit lamps

A metal body shrugs off the knocks a glass bowl would not survive and will not shatter if it rolls off the counter, so it earns its place at a busy chairside or in a mobile kit. The GI Dental Spirit Lamp is a stainless model with a screw cap.

Angular and flame-control lamps

Some lamps tilt the wick or add an adjuster collar so the flame can be worked upright or on a slant and turned down to a fine tip for delicate warming. The Maarc Spirit Angular Lamp With Flame Control (5505/G/001) does both.

Base and combination models

A base or combination lamp pairs a weighted stand with a swappable glass or metal bowl, so one holder covers both preferences and a cracked bowl can be replaced on its own. The Samit Spirit Lamp ships in glass and metal options on a single base.

When a spirit lamp is used

A spirit lamp comes out whenever a warm tip or a quick flame does a job better than a cold instrument:

• Flaming a wax carver, PKT, or Le Cron before it shapes inlay or pattern wax
• Softening modelling and sticky wax for a bite rim, a repair, or a try-in
• Warming a cone from the gutta percha points tray so it adapts to the canal wall during condensation
• Passing a probe or explorer briefly through the flame for a quick chairside decontamination
• Flame-polishing the finished edge of an acrylic denture or an orthodontic plate
• Heating a plastic instrument for die-spacing or wax-pattern work at the lab bench

How to choose a spirit lamp

1. Bowl material — glass to keep an eye on the spirit level, steel to survive the drops a clumsy bench delivers.
2. Flame control — a plain fixed wick is fine for routine warming; an adjuster collar or angular head earns its keep where the flame has to tilt or throttle down.
3. Cap and seal — a cap that seats properly snuffs the flame and stops the spirit evaporating away between sessions.
4. Reservoir size — a larger bowl runs a full lab session without a refill; a smaller one is lighter and dries out slower on a lamp used only now and then.
5. Wick access — a lamp whose wick pulls out for trimming or replacement outlasts one where the wick is sealed in.

Spirit lamp brands on Dentalkart

Samit accounts for most of the lamps on this page, in both glass and metal bowls at the lowest price per unit, which is why a college bench or a clinic buying a handful at once tends to start there.

GI's stainless lamp is the one to pick where the bowl takes daily handling, and Maarc's angular flame-control lamp is what you reach for when the flame has to tilt or drop to a fine point for close work.

Why buy a spirit lamp from Dentalkart

A spirit lamp costs little and lasts for years, which puts the weight on the small things that let a cheap lamp down — a cap that seals tightly enough that the spirit does not evaporate to nothing over a weekend, a wick that pulls free for trimming, and a bowl that either shows the level or shrugs off a fall. Between them the three makes stocked here cover the glass route, the steel route, and the flame-control option, at prices low enough to justify keeping a spare in the drawer, and they sit in the same catalogue as the wax, gutta-percha, and hand instruments the flame is actually lit for.

What is a spirit lamp used for in dentistry?

A spirit lamp gives a clinic or lab a small open flame for the jobs a warm tip does better than a cold one — flaming a wax carver, softening modelling wax, warming a gutta-percha cone, flame-polishing acrylic, or passing an explorer briefly through the heat. It stands in for a gas burner wherever none is plumbed in.

Glass or stainless steel — which bowl should I pick?

Neither wins outright; it comes down to the bench. A glass bowl shows the spirit level so you refill before the wick runs dry, which suits a shared teaching lab. A steel bowl cannot shatter and takes daily knocks, which suits a busy chairside. Choose by whichever risk your bench runs into more often.

What fuel does a spirit lamp burn?

A spirit lamp burns denatured alcohol — methylated spirit or ethanol sold as lamp spirit — drawn up through a cotton wick. It should never be filled with petrol, kerosene, or any other fuel, which flare and soot. Fill to about two-thirds so there is room for vapour, and wipe any spill off the outside before lighting.

Can a spirit lamp actually sterilise instruments?

Not fully — passing an instrument through the flame is flaming, not sterilisation. The heat kills surface organisms and is useful for a quick chairside decontamination, but it does not reach or hold the temperature and time an autoclave does, so spores survive. Keep the lamp for warming and a quick flame, and use an autoclave for true sterilisation.

How do I keep the flame steady and the lamp lasting?

Trim the wick flat and leave only 5–6 mm proud, so the flame burns low and blue instead of tall and sooty. Cap the lamp the moment you finish to snuff it and stop the spirit evaporating, top up before the wick runs dry, and swap the wick once it has charred down.
