Usbeck Bunsen burner, lever tap, pilot flame, air regulation
The Bunsen burner presented here is a particularly versatile solution for numerous applications in the laboratory environment. It is ideal for natural gas or propane gas and features a straight burner tube and precise air regulation via a sliding air sleeve. A significant advantage over similar burner models is the integrated pilot flame feature, which allows the flame to continue burning minimally even when closed to make relighting easier. Thanks to its robust construction, the burner is designed for continuous operation and complies with important standards, making it a reliable tool in professional laboratories.
Versatile features for efficient laboratory operation
The intelligent combination of lever tap and needle valve allows the gas supply to be optimally adjusted, ensuring a high level of efficiency in everyday laboratory work. The appliance is also impressive when it comes to safety: when used in accordance with DIN 30665, the standard stipulates that the flame cannot be switched off completely, but a very small flame remains, which can be regulated up again immediately if required. The gas tap on the central laboratory gas supply should of course always be carefully closed when the burner is no longer in use.
Overview of important technical data:
- Max. Temperature: 1500 °C (natural gas) or 1520 °C (propane gas)
- Consumption: 100 l/h (natural gas) or 55 l/h (propane gas)
- Load: 1.1 kW (natural gas) or 1.25 kW (propane gas)
- Height: 155 mm
- Tube diameter: 14 mm
- Head diameter: 17 mm
- Optional adhesive base available
All versions of the torch measure 155 mm in height and weigh around 245 g. The attachment diameter of 14 mm is ideal for customisation in different laboratory situations in order to precisely shape the flame height. The lever tap also makes it particularly easy to switch between the pilot and working flame.
In chemical, biological or medical laboratories in particular, precise control of the heat output is always important. The variable air control allows users to set the flame from bright yellow to almost colourless (blue flame), which is required for applications such as sterilisation work, ash determination or concentration determination. This burner is also suitable for research projects in which, for example, reaction mixtures are heated or samples are dried. As the flame only burns at a low level when required, users save valuable gas and benefit from cost-effective laboratory operation.
As it is optionally available as a DIN burner, it can be supplied with the corresponding certifications. This offers additional safety and makes it easier to use in specially regulated areas. In DIN-compliant operation, the flame cannot be switched off completely in accordance with standard 30665, which offers the advantage of a constant ignition point. Users who need to switch quickly between off and full operation in practice benefit from this design, but must always use the central shut-off to ensure complete disconnection from the gas network.
Concrete application examples
- Heating test tubes during chemical reactions to achieve exact temperatures.
- Sterilising metal spatulas, inoculation loops or smaller glassware in microbiology laboratories.
- Drying or heating samples in food analysis for water or fat determination.
- Short-term flaming of surfaces in biotechnology to prevent contamination.
The high temperature stability is a particular advantage in applications with organic substances. Solvent residues can be evaporated in a controlled manner before further analysis steps take place, while in metallurgy, smaller pieces of metal can be briefly heated, melted or soldered on.
FAQs
How long can the pilot flame be operated?
The pilot light is designed for continuous operation and can burn until it is switched off via the central gas supply.
Which types of gas are recommended
Natural gas and propane gas are used very frequently. Both develop high temperatures, with propane gas reaching a maximum of around 1520 °C, slightly higher than natural gas.
How can the flame size be regulated?
The flame height is controlled by the lever tap and the needle valve. The side air sleeve determines the ratio of gas to air and influences the flame colour.
Is there a special certification?
The burner can be supplied either without or with DIN 30665, which then results in further requirements in accordance with DIN-DVGW reg. no. NG-2211AN0133.
Conclusion
This powerful Bunsen burner with integrated functions such as pilot flame and precise air regulation is a recommended solution for a wide range of laboratory tasks. Thanks to the lever tap, variable gas supply and reliable design, it can be adapted precisely to individual requirements. In particular, its high temperature output and selectable DIN 30665 certification make it a reliable tool in professional environments. With its robust design, adjustable operating modes and the optionally available adhesive base, nothing stands in the way of flexible use in everyday laboratory work.
