Laboratory Gas Burners - applications
Gas burners are important items of laboratory equipment for achieving high temperatures in the laboratory, such as for the flame treatment or sterilisation of laboratory vessels and instruments or inoculation loops. Our laboratory gas burners by the manufacturers WLD-TEC or BOCHEM are suitable for almost all flame-requiring applications in the laboratory, whereby the safety gas burners are mainly used in chemical laboratories, in research institutions in the fields of biotechnology, microbiology or cell biology, as well as in universities, specialist colleges and school laboratories.
A laboratory Bunsen burner is a small gas burner which, in addition to the Teclu burner, is often used on the laboratory bench for the short-term heating of material samples or liquids and is mainly used for preliminary samples in analytical chemistry, e.g. for blowpipe analysis, borax or phosphorus bead testing and flame testing. Additionally, laboratory gas and Bunsen burners are also used to heat various dishes in molecular kitchens.
Bunsen Burner - function
Bunsen burners are usually operated with town gas, natural gas, propane or butane. Based on the operating principle of a jet pump, the respective combustion gas itself draws in the required combustion air through a small opening. In terms of construction, a traditional Bunsen burner usually consists of a burner base, a gas regulating screw, a gas nozzle, a burner tube, a flue gas attachment and gas and air supply. Classic Bunsen burners consist of an approx. 15 cm long metal pipe, at the upper end of which the gas is ignited with a match, gas lighter or flint. Advanced safety bunson burners such as the Flame 100 start immediately at the press of a button. Optionally this laboratory gas burner can also be operated via a foot pedal or an external IR motion sensor.
Furthermore, in modern Bunsen burners, a grid or fine drilled holes prevent(s) flash-back of the flame into the burner. In the combustion tube/outlet the gas flows upwards and is regulated at the lower end of the burner with a gas regulating screw. This screw is conical and closes off the gas supply. The laboratory gas burner stands on a heavy metal foot, which ensures that the Bunsen burner stands securely on the laboratory table. The air and combustion gas supply are attached to this base. Connected to the gas tap is a flexible gas pipe through which the gas is supplied. Oxygen enters the Bunson burner through the air-regulating screw. When this is opened and the oxygen in the burner mixes with the combustion gas, a blue, very hot premix flame is produced. The flame heat can be regulated between 350 and approx. 1000 °C, in the case of the Teclu burner 1300 °C. Without the supply of air, the flame is yellow and not as hot. When the opening is closed, the combustion gas mixes only with the oxygen at the upper outlet of the burner tube and reaches lower temperatures, whereas such a yellow diffusion flame can be up to 900 °C cooler.
Laboratory Gas and Bunsen Burners - start-up procedure
When operating a gas burner in the laboratory, make sure that the air regulating screw and the gas regulating screw are closed. It must then be checked that the energy supply to the laboratory gas burner is connected and the funnel of the Bunsen burner is firmly connected to the threaded part. The gas burner is generally put into operation as follows: open the main gas valve and switch on the electrical gas safety device; check that the air and gas regulation screws are closed; slightly open the gas regulation screw and immediately ignite the escaping gas; open the gas and air regulation screws until the desired flame is produced.
Generally, the laboratory gas burner is switched off in the appropriate manner; close the air and then the gas regulating screw, close the gas valve at the workplace on the laboratory bench; turn off the main electrical fuse and check all gas taps.
Laboratory Gas and Bunsen Burner - accessories
Our high-quality laboratory gas burners and bunson burners are characterised by a maximum degree of safety, extreme comfort and economical energy consumption - as well as the possibility of changing or adding individual components. Depending on the gas burner and manufacturer you can order many different replacement parts and gas burner accessories.
Our Bunsen burner ranges include, for example, gas cartridges, gas hoses, ceran protection plates, safety hoses, IR motion sensors, foot pedals, inoculation loop holders, safety adapters, wind protection or stainless steel burner heads and many other components for the laboratory gas burners we have on offer.
