The device is particularly impressive in a professional environment thanks to its compact design, user-friendly handling and robust workmanship. Thanks to its needle valve and side air intake, the flame intensity can be adjusted cleanly and stably, which guarantees greater reproducibility and safety compared to other devices when heating, sterilising or developing a wide variety of experiments.\u003c\/p\u003e\n\n\u003cp\u003eSophisticated design for demanding tasks\u003c\/p\u003e\n\n\u003cp\u003eThe burner has a straight burner tube through which the gas is channelled. An adjustable air sleeve allows the air supply to be regulated as required so that users can precisely adjust the flame characteristics. Anyone working with different types of gas, such as natural gas or propane gas, will find a flexible solution for various laboratory situations. Temperatures of up to 1500 °C can be achieved with natural gas and up to 1550 °C with propane gas, which is crucial for many applications such as annealing metals or heating samples quickly.\u003c\/p\u003e\n\n\u003cp\u003eThe appliance is also available in a DIN version in accordance with DIN 30665 and can be supplied with DIN-DVGW reg. no. NG-2211AN0133 on request. Please note that the DIN versions cannot be switched off completely. This means that the burner maintains a small flame even when the needle valve is closed. The central shut-off in the laboratory is then required to switch it off completely. This complies with the special specifications for DIN burners and serves to increase operational safety by preventing the unintentional escape of gas.\u003c\/p\u003e\n\n\u003cp\u003ePerformance features and technical details\u003c\/p\u003e\n\n\u003cp\u003eThe most important key figures, which provide guidance for the precise planning of test set-ups or laboratory processes, can be summarised in a nutshell:\u003c\/p\u003e\n\n\u003cp\u003e- Available as DIN or non-DIN version for different regulations\u003cbr\u003e\n- For natural gas: flame temperature up to 1500 °C, gas consumption approx. 110-115 l\/h, power consumption approx. 1 kW\u003cbr\u003e\n- For propane gas: flame temperature up to 1550 °C, gas consumption approx. 55 l\/h, power consumption approx. 1.7 kW\u003cbr\u003e\n- Weight of 220 g and height of 155 mm for stable positioning on the laboratory bench\u003cbr\u003e\n- Robust burner tube with 14 mm diameter and burner head with 17 mm diameter\u003cbr\u003e\n- Optional adhesive foot solution for secure fixing at the workstation\u003cbr\u003e\n- Needle valve for precise adjustment of the gas flow\u003c\/p\u003e\n\n\u003cp\u003eThis opens up a wide range of possible applications: The burner is suitable for flame sterilisation of laboratory utensils such as inoculation loops or spatulas, for annealing reaction vessels and for rapid heating of liquids.
