Spirit Burner for Science Laboratory

Product Code : SCL-CL-12017

The Spirit Lamp is a heavy-duty, glass-walled laboratory heating vessel used for generating a localized open flame via alcohol fuel combustion. Designed for chemistry students, biology technicians, and field researchers, this portable glass burner delivers stable, low-intensity heat for basic sterilizations, microscale distillations, and standard scientific experiments.

Product Description

The Spirit Lamp 100mL from Science Lab Supplies provides excellent thermal stability and operational utility for school classrooms, university labs, and industrial research benches. Fabricated from premium, low-expansion borosilicate glass, the reservoir body features uniform wall thickness to ensure resistance against high thermal stress and mechanical impacts. The heavy-walled glass base is molded with an extra-wide footprint to enhance physical stability and prevent accidental tipping on crowded work surfaces.

This classic laboratory glass alcohol burner is equipped with a precision-ground glass snuffer cap and a ceramic wick holder core. The tight-fitting ground glass joint ensures that the fuel reservoir remains completely sealed when inactive, reducing fuel evaporation and protecting contents from external contaminants. As a core component within our comprehensive array of laboratory heating instruments, this reusable spirit lamp delivers long-lasting field performance without needing external gas lines or electricity.

Key Features

• Premium Borosilicate Glass: Molded from heat-resistant, low-expansion glass that safely handles long heating cycles without cracking.
• Airtight Ground Glass Cap: Features a precision-ground snuffer cap that smothers the flame instantly and prevents alcohol fuel evaporation during storage.
• Stable Anti-Tip Profile: Engineered with a wide, heavy-bottomed circular base to maximize stability on laboratory benches.
• High-Absorbency Cotton Wick: Outfitted with a durable, woven cotton wick that draws liquid fuel smoothly to ensure a steady, soot-free flame.
• Interchangeable Ceramic Core: Includes a non-combustible ceramic wick holder that fits snugly into the bottle neck to minimize fuel splash risks.
• Excellent Fluid Visibility: Crystal-clear glass body allows laboratory personnel to visually track fuel levels easily before starting procedures.

How to Use the Spirit Lamp

1. Inspect the glass body, neck, and ground glass cap for any chips, micro-fractures, or structural flaws before lighting.
2. Remove the glass snuffer cap and slide the ceramic wick holder out of the neck opening.
3. Pour denatured alcohol into the glass reservoir using a small plastic funnel, filling it to roughly 75% to 80% capacity.
4. Thread a clean cotton wick through the ceramic core, insert the assembly back into the neck, and wait 3 minutes for the wick to saturate.
5. Strike a match or utilize a long-reach electronic lighter to ignite the top tip of the exposed wick away from drafts.
6. Extinguish the flame completely by placing the matching ground glass cap directly over the active wick assembly.

Handling Note: Never attempt to refill the glass reservoir while the lamp flame is actively burning or while the glass structure remains hot. Do not blow on the active flame to extinguish it; always utilize the ground glass cap to starve the fire of oxygen safely.

Care & Maintenance

• Fuel Management: Empty all remaining alcohol fuel from the glass reservoir if you intend to store the device unused for longer than two consecutive weeks.
• Wick Optimization: Trim away charred or heavily carbonized sections of the cotton wick regularly to prevent excess soot and ensure a clean flame shape.
• Glass Decontamination: Wash the glass parts with a mild, non-abrasive detergent, rinse with distilled water, and dry completely before reassembling.

Frequently Asked Questions

What is a Spirit Lamp used for?

It is a portable, open-flame heating instrument used to sterilize biological tools, boil small test tube solutions, and perform microscale chemical experiments. Because it does not require external utility connections, it is highly suited for field studies and introductory classrooms.

What fuel should I use inside this glass alcohol burner?

This lamp is engineered to run exclusively on high-purity denatured alcohol, industrial methylated spirits, or ethanol with an alcohol concentration exceeding 90%. Never utilize gasoline, kerosene, or lighter fluid, as these generate explosive vapor patterns.

Can this glass lamp crack under direct flame exposure?

No, the reservoir is manufactured from premium, low-expansion borosilicate glass which features high thermal shock resistance and low thermal expansion parameters, making it completely safe for standard laboratory heating workloads.

How do I safely put out the flame?

To put out the flame safely, place the included ground glass snuffer cap directly over the burning wick. This cuts off the oxygen supply and smothers the flame instantly. Never attempt to blow out the flame manually.

Is this instrument suitable for high school science labs?

Yes, it is widely used in middle schools, high schools, and universities due to its anti-tip design, heavy-walled construction, and ease of use for introducing students to open-flame techniques.
