Usbeck safety burner, DIN, G 1/4 left-hand thread, safety pilot, needle valve
This safety burner is primarily used in professional laboratory environments where high reliability, maximum safety and precise flame regulation are essential. Compared to conventional burners, this model offers an integrated ignition safety device and a needle valve for particularly precise control of the flame intensity. It also complies with DIN 30665, making it the preferred choice for laboratory technicians who need a robust and standard-compliant burner.
Precise flame control and safety features
The burner has a built-in pilot flame and its needle valve allows the gas flow to be finely adjusted. This is particularly helpful for experiments that require different heat levels, for example when melting small glass tubes or heating sensitive chemicals in reaction vessels. Thanks to its design in accordance with DIN 30665, the gas cannot be completely switched off at the appliance itself. Therefore, the pilot flame continues to burn even when the needle valve is closed and the gas supply should be deactivated at the central supply point in the laboratory. The integrated ignition safety device also prevents unwanted gas build-up should the flame go out.
Important features at a glance
- Suitable for natural gas and propane gas
- Temperature range up to 1550 °C
- DIN-compliant design in accordance with standard 30665
- G 1/4 left-hand thread for secure hose connection
- Economy flame with air regulation for constant burning performance
- Robust construction for professional laboratory use
- Stable stand optionally available
With its 13 mm large combustion tube and 17 mm wide burner head, flames are evenly focussed and concentrated. The robust housing weighs just 400 g and is therefore easy to handle and uncomplicated to place. With a height of 160 mm, the device fits into standard fume cupboards without taking up valuable space. If required, you can also use an adhesive base to increase stability.
The different types of gas support different temperatures and outputs. With natural gas, a throughput of 110 l/h is possible with a heat output of around 1.5 kW; with propane gas, the consumption is 65 l/h and even reaches 1.7 kW. Both variants achieve flame temperatures that are typically between 1520 °C (natural gas) and 1550 °C (propane gas). This makes the appliance equally suitable for standard sterilisations as well as more demanding applications, such as melting glass capillary tubes or heating highly viscous substances.
Compliance with relevant standards
As the device is designed in accordance with DIN 30665, it can be used in laboratories that are subject to strict safety requirements and certifications. In combination with a central gas shut-off and tested connection materials, reliable work processes are guaranteed. The ignition safety device acts as a key safety feature and prevents unwanted gas leaks if the burner goes out unintentionally.
Concrete application examples
- Sterilisation of inoculation loops in microbiological laboratories
- Careful heating of temperature-sensitive substances such as agarose or gelatine solutions
- Annealing small glass or metal parts in chemical experiments
- Point and line heating in glass processing, especially for delicate reaction apparatus
The precise flame control also makes the device suitable for heating solvents such as ethanol or isopropanol and allows a level of safety that meets the high requirements of a professional laboratory.
Frequently asked questions
How can I safely clean the burner
?
Use a soft cloth to carefully remove any visible dirt or deposits first. A special brush for gas nozzles can then be used to thoroughly clean the inside. Make sure to close all gas pipes and allow the burner to cool down completely.
Is it possible to switch off the gas completely at the burner?
No, this model in accordance with DIN 30665 retains a small pilot flame even when the needle valve is closed. The gas supply should therefore always be interrupted via the central shut-off in the laboratory.
Can I use natural gas and propane gas at will?
Yes, the burner is designed for both types of gas. Make sure you use the appropriate hose connection and the recommended settings for air supply and output to achieve the optimum flame temperature.
Which hose connectors are available
Optional hose connection pieces with G 1/4 left-hand thread are available. An order can be placed as required to ensure a secure connection to your existing gas hoses.
Summary
This model offers a reliable flame source for a wide range of laboratory applications, from microbiological work to demanding glass working processes. Thanks to its compliance with standards and robust design, it is suitable for environments where safety and precision are top priorities. The high flexibility with regard to gas types, the integrated ignition safety device and the easily adjustable needle valve make it a versatile tool for professional requirements.
