Usbeck Bunsen burner, DIN, double lever, pilot flame, air regulation
This burner is ideal for precise laboratory applications that require a controlled gas supply. Thanks to the robust double-lever design and an integrated pilot flame, it offers a particularly high level of safety and precise adjustment options. Compared to many standard laboratory torches on the market, it impresses with its reliable performance, flexible air regulation and certified quality in accordance with DIN standards.
Versatile application options and decisive advantages
This Bunsen burner is specially designed for the professional laboratory sector, where constant yet energy-efficient flames are required. The adjustable air sleeve enables precise adjustment of the air/gas mixture and therefore optimum flame characteristics: the flame temperature can be increased or decreased depending on requirements without compromising on safety. Various flame strengths can be controlled quickly and easily using the double lever, which saves considerable time in day-to-day laboratory work and makes the workflow more fluid.
The pilot flame of the burner can offer considerable advantages, especially if it is switched on and off frequently: It enables a quasi-standby mode in which little gas is consumed, but at the same time the flame always remains ready to ignite. If the valves are fully closed, a small flame continues to burn according to the standard; it is therefore recommended that the gas supply is interrupted on site or centrally in the laboratory.
Technical data at a glance
- Suitable for natural gas or propane (temperatures up to 1480 °C for natural gas and 1500 °C for propane)
- Double lever system for main and pilot flame
- Adjustable air sleeve for optimum air regulation
- Compact dimensions: Height approx. 155 mm, tube diameter 14 mm, head diameter 17 mm
- Load: approx. 1.10 kW (natural gas) and 1.25 kW (propane)
- Gas consumption: approx. 90 l/h (natural gas) and 55 l/h (propane)
- Low weight of around 235 g
Additionally, an adhesive base is available as a practical option, allowing the burner to be attached even more securely to the laboratory bench. Thanks to its low weight and clear housing structure, it is easy to handle and can also be used for longer periods without any problems.
The integrated double lever technology ensures a quick changeover between full flame and practical pilot flame. This is particularly helpful when an ignition source is required repeatedly at short intervals, for example in microbiological, chemical or analytical laboratory procedures in which test tubes, Petri dishes or other materials often need to be heated or sterilised briefly.
Certifications and standards
The burner complies with the requirements of DIN standard 30665 and bears the DIN-DVGW reg. no. NG-2211AN0133. These certifications confirm compliance with important safety-related requirements and ensure a high level of reliability in everyday laboratory use. Users therefore not only benefit from the manufacturer's many years of experience, but can also rely on clearly defined standards when it comes to safe operation and quality.
Concrete application examples
- Sterilisation in microbiology: For rapid and germ-free annealing of inoculation loops, needles or forceps.
- Heating samples for analysis purposes: Ideal in inorganic chemistry to easily heat test substances and observe reaction processes.
- Flamination tests for substance identification: The colour appearance of certain metal ions (e.g. sodium, potassium, copper) can be quickly assessed.
- Flame treatment of glassware: Precise, selective heating can be achieved for short-term sterilisation or for modifying thin-walled glass tubes.
FAQs
How does the burner react to different gas qualities?
It is designed for both natural gas and propane. The air regulation and the double lever ensure a stable and adjustable flame for both types of gas.
How is the flame regulated?
Through an adjustable air sleeve and the double lever system. This allows the mixing ratio of air and gas to be precisely adjusted, enabling both a strong main flame and a small pilot flame.
What to look out for in terms of safety
As the burner cannot be completely closed in accordance with DIN 30665, the gas line should be turned off via the central shut-off valve when the burner is not in operation. A stable stand and a clean working area are also crucial.
Can the burner remain in economy mode permanently?
Yes, permanent operation with economy flame is technically possible, but for safety and efficiency reasons it is recommended that the gas supply is always interrupted after use.
Is the product suitable for classroom use?
Due to the high safety standards and simple operation, the burner can be used in professional laboratories as well as in commercial or academic training centres.
Conclusion
This laboratory blowtorch is characterised by flexibility, safety and precise flame control. The robust design, the patented double lever principle and the sophisticated air regulation ensure convenient and reliable operation. Thanks to its standard-compliant certification and easy handling, the appliance is the ideal companion for a wide range of laboratory applications that require a precise and permanently stable flame.
