Guide and selection support
Burners, such as Bunsen or Teclu burners, are mainly used in laboratories for heating samples, liquids, and for flaming purposes. They usually operate with gases such as propane, butane, or natural gas, and are indispensable for many chemical applications.
Important factors when selecting a burner include the type of fuel gas, flame stability, safety features against flashback, and ease of handling. Burner designs and equipment differ depending on laboratory requirements.
LabFinder helps users quickly find their way by providing a clear overview of laboratory burners. This makes it easy to find and procure the appropriate gas burner design for specific applications.
Application and Benefits
Burners such as Bunsen and Teclu burners are gas-powered laboratory devices primarily used in chemistry labs for heating liquids or samples. They are also utilized for flaming, such as in sterilizing laboratory tools or experimental glassware. The flame is produced by burning a fuel gas, which typically draws in air based on the ejector principle, generating a hot and adjustable flame.
Selection Criteria
Key factors for selection include the type of fuel gas used (propane, butane, natural gas), flame stability, protection against flashback, and easy flame adjustment. Material quality and the ability to adjust the flame (flame height, air/gas ratio) are also important. Proper connections to the gas supply must be ensured.
Variants and Functionality
The most common variants are the Bunsen burner and the Teclu burner. Both gain combustion air by air intake via the gas flow and generate a hot, adjustable gas flame. Modern burners often feature safety elements, such as a flashback arrestor grid or finely perforated holes on the burner head to prevent flashback. Burners differ in air supply design and flame characteristics.
Calibration and Maintenance
Burners do not require calibration, but should be regularly checked for integrity, cleanliness, and safe function. Especially the burner head should be free of blockages to ensure stable flame operation. Rubber hoses and connections should be inspected for tightness and wear. Cleaning and maintenance measures contribute to the safety and longevity of burners.
Limitations of Use
Burners are not suitable for heating in closed systems, as open flames and gas leaks at the connector can pose hazards. Use in explosive atmospheres is also restricted and requires specialized equipment and safeguards. Burners do not replace electric heating equipment for sensitive applications or where precise temperature control is needed.

Frequently asked questions
How does a Bunsen burner work?
A Bunsen burner produces a hot gas flame by burning fuel gas (usually propane, butane, or natural gas). The combustion air is drawn in and mixed with the gas through a valve and then ignited.
What types of burners are there and how do they differ?
The most common types are Bunsen burners and Teclu burners. Both use the principle of a gas-driven flame but differ in the way they supply air and in flame characteristics. Modern devices are often equipped with safety features to prevent flashback.
What are important criteria when selecting a burner?
Important aspects include the type of gas used, flame adjustability, safety features such as flashback arrestors, connection compatibility, as well as ease of use and maintenance.
How is a gas-powered burner maintained?
Regularly check the connections for leaks, clean the burner head, and test the safety features. There is no calibration requirement, but contamination and damage should be remedied in a timely manner.
What are the application limits for laboratory burners?
Burners are not suitable for closed systems or for explosive atmospheres without special safety equipment. Precise temperature control is also generally not possible with gas burners.
