Usbeck Bunsen burner, DIN, needle valve, air regulation
This powerful laboratory burner offers precise and reliable flame control for a wide range of experiments and applications in heat treatment, sample analysis or material processing. Thanks to its robust design and sophisticated air regulation, it is particularly suitable for laboratories, schools and industrial research facilities that value high safety standards and reliable performance. This burner stands out from comparable devices thanks to its ease of use, standard-compliant design and efficient gas utilisation.
Features and functionality
The appliance impresses with a straight burner tube and a lateral air intake that can be easily adjusted using a sliding sleeve. This allows the gas/air mixture to be optimally adjusted to the required flame intensity. The integrated needle valve allows refined control of the gas supply and ensures constant, clean combustion. As this is a DIN burner in accordance with standard 30665, it should be noted that the gas supply is not completely shut off: A small flame remains, even when the gas tap is closed. In everyday laboratory work, the central gas shut-off also guarantees maximum safety.

- Max. Temperature: approx. 1500 °C (natural gas) or 1540 °C (propane)
- Low consumption: 110 l/h for natural gas and 55 l/h for propane
- Nominal load of around 1.25 kW (natural gas) or 1.35 kW (propane)
- Height: approx. 155 mm for easy handling
- Sturdy tube diameter of 14 mm and head diameter of 17 mm
- Weight: only approx. 210 g, optionally available with adhesive base
In addition, high-quality materials ensure a long service life under demanding conditions. The design complies with the requirements of DIN 30665, which is also confirmed by DIN-DVGW reg. no. NG-2211AN0133. These certifications make it clear that the appliance fulfils strict quality guidelines and meets the highest standards in terms of safety. For those looking for a flexible solution for various laboratory activities, the gas burner delivers consistent and reproducible results.
Certifications and standards
The burner fulfils the requirements of DIN 30665, which precisely defines the design and function of laboratory burners. It also has DIN-DVGW registration, which underpins its suitability for safe use with gases. Users can rest assured that production is carried out in accordance with recognised standards and that trouble-free operation is guaranteed even in intensive laboratory applications.
Concrete application examples
- Digestion of substances in inorganic chemistry: The constant flame temperature simplifies the safe heating of samples, for example metal salts or oxides.
- Sterilisation in the microbiology laboratory: culture media, Drigalski spatulas or inoculation loops can be efficiently scorched without the risk of contamination from irregular flames.
- Test set-ups in thermodynamics: The precisely adjustable flame intensity offers flexible application options for heating reaction vessels or demonstrating various combustion processes.
- Combustion of chemical waste in very small quantities: Safe handling thanks to uniform heat development reduces the risk of sudden temperature peaks.
These practical examples illustrate how versatile the device can be. Whether in the classroom, in product development or in research, the control of flame formation and temperature is always guaranteed.
FAQs
How to set the flame intensity correctly
The flame intensity is mainly regulated via the needle valve, which reduces or increases the gas flow. At the same time, the adjustable air supply influences the intensity and burning behaviour.
May the appliance be switched off completely?
In accordance with DIN standard 30665, DIN burners are not completely sealed. A small flame continues to burn when the needle valve is turned off, which is why the gas flow should always be interrupted at the central laboratory shut-off.
What types of gas can be used
The burner is designed for operation with natural gas and propane. The maximum temperature varies slightly depending on the gas: approx. 1500 °C for natural gas and around 1540 °C for propane.
Can the burner be additionally protected?
Yes, an adhesive base is available on request for this model, which gives the appliance more stability and safety, especially if frequent repositioning is required in the laboratory.
Is maintenance time-consuming?
Maintenance is straightforward. The burner should be checked regularly for soiling and cleaned carefully. The needle valve is easy to clean so that the gas supply always remains even.
Conclusion
This model impresses with its precise flame regulation, high level of safety and flexible application options in various laboratory areas. The robust workmanship, compliance with important standards and versatile connection options to natural gas or propane make the burner an indispensable tool for professional work. Users benefit from a reliable, easily controllable heat source that can be seamlessly integrated into various laboratory contexts and ensures efficient and safe operation.
