The Rothenberger Industrial Multigas 300 is a professional butane/propane gas cartridge with 600 ml of fuel per cartridge, supplied in a practical 2-piece Duopack. With a self-sealing 7/16" EU connection compliant with the EN 417 standard and a flame temperature of up to 1,900 °C, it is the reference cartridge for kitchen torches and workshop burners, combining clean combustion, a stable flame and long working autonomy.
What the Multigas 300 is
Multigas 300 is the model name of one of Rothenberger Industrial's best-known fuel-gas cartridges; the figure 300 identifies the line, not the volume, which is 600 ml per cartridge (net weight about 338 g). Rothenberger is a German manufacturer specialising in technical gases and professional tools for soldering, brazing and flame work. The gas is a dewaxed butane/propane mixture (roughly 70% butane, 30% propane) refined to a high degree of purity, which is exactly what makes the flame stable, controllable and free of the impurities that would taint food during finishing tasks.
Technical profile
The cartridge reaches a flame temperature of up to 1,900 °C with a typical working temperature of 700-750 °C, enough for caramelising, gratinating, searing, soft soldering and brazing. The 7/16" EU thread is the European standard fitting and makes the cartridge compatible with the vast majority of professional torches and burners on the market, including the Kisag caramelising torch. The self-sealing valve (EN 417) closes automatically when the cartridge is removed from the appliance, so it can be detached safely between uses without gas loss. Classification: UN 2037, article number 035510.
Professional uses in the kitchen
In the professional kitchen the Multigas 300 powers the gas torch for the finishing tasks that define modern plating: caramelising the sugar crust of crème brûlée to an even amber in seconds, glazing and gratinating gratins and meringues à la minute, searing the surface of meat, fish and tataki without overcooking the core, blistering the skin of peppers, and melting or marking sugar and chocolate decorations. The adjustable, clean flame lets the pastry chef and the line cook work directly on the plate at the pass, an immediacy that no oven or salamander can match.
Professional uses in the workshop
The same cartridge is a true multi-purpose fuel: with a soldering torch it handles soft soldering and brazing of copper pipes and fittings, heating and loosening seized parts, shrinking heat-shrink sleeves and light flame work. This dual culinary-and-technical vocation is the reason the Multigas 300 is a fixture in both restaurant kitchens and maintenance workshops.
Pairings and accessories
The Multigas 300 is designed to be used with a compatible 7/16" EU torch or caramelising burner; pair it with the Kisag caramelising torch, with refillable kitchen torches and with the other workshop and service consumables in the LAPA Non-Food range. Keeping a Duopack on hand means a professional station never runs out of fuel mid-service.
Storage and safety
Pressurised gas cartridge: store upright in a cool, ventilated place, away from heat sources, sparks and open flames, and do not expose to temperatures over 50 °C. Do not pierce or burn the cartridge, even when empty, and keep out of the reach of children. Each cartridge contains 600 ml; the Duopack provides two, covering the needs of a busy kitchen or workshop without interruption.
