Thanks to its robust design, prominent hot surface warning and precise temperature control, it offers high reliability, safety and durability compared to similar products.\u003c\/p\u003e\n\n\u003cp\u003eReliability and ease of use\u003c\/p\u003e\n\n\u003cp\u003eThis heating stirrer system has been specially developed for the rapid heating of liquids up to 500 °C (depending on the model also up to 380 °C with ceramic-coated steel plates) and ensures consistent stirring performance at speeds of 80 to 1,600 rpm. Users benefit from a clear user interface with an easy-to-read LCD display that shows both current temperature and speed data. A clearly visible indicator light warns as soon as the plate reaches a temperature above 40 °C.\u003c\/p\u003e\n\n\u003cp\u003e- Capacity up to 15 litres\n- Plate sizes: 102 x 102 mm, 178 x 178 mm or 135 mm (round)\n- Temperature range: Up to max. 500 °C or up to 380 °C (ceramic-coated steel)\n- Digital control and LCD display\n- Power: 550 W or 1050 W depending on version\n- TÜV-certified\u003c\/p\u003e\n\n\u003cp\u003eThe metallic housing structure is designed so that dirt can be easily removed. In addition, the hard-wearing design and chemical-resistant surface coating make the device a reliable partner for everyday laboratory work. An integrated stand rod holder makes it easy to attach sensors such as Pt1000 to ensure precise measurement results in the test setup. The space-saving dimensions and the powerful heating system round off the overall package.\u003c\/p\u003e\n\n\u003cp\u003eIn addition to safety aspects such as the SafetyHeat early detection system, which stops the heating function in good time in the event of temperature deviations, the button for switching off the heating is also located in the front area and is easily accessible. The green status indicator lights up when heating and stirring are in progress and switches off as soon as these functions are complete.Standards and certifications\u003c\/p\u003e\n\n\u003cp\u003eThe heating stirrer is tested in accordance with TÜV specifications. This shows that the manufacturer follows the highest safety standards during development. This certification gives laboratory users additional safety in daily use, especially in sensitive areas where consistent and reproducible conditions are required.\u003c\/p\u003e\n\n\u003cp\u003eConcrete application examples\u003c\/p\u003e\n\n\u003cp\u003e- Preparation of buffer and reagent solutions in biotechnology to gently mix sensitive enzymes or proteins at stable temperatures\u003cbr\u003e.\n- Carrying out syntheses in chemical research in which substances such as alcohols or acids are heated and stirred evenly.\u003cbr\u003e\n- Condensation processes in pharmaceutical development, for example when evaporating or heating samples before analysing them.\u003cbr\u003e\n- Media preparation in microbiology, for example in the production of culture media for various microbial cultures that require precise temperature control.\u003c\/p\u003e\n\n\u003cp\u003eFrequently asked questions\u003c\/p\u003e\n\n\u003ch3\u003eHow is the temperature fully controlled\u003c\/h3\u003e\n\n\u003cp\u003e?\u003c\/p\u003e\n\n\u003cp\u003eThe optional Pt1000 temperature probe can be connected to measure the sample temperature directly in the vessel. This compensates for deviations in the plate surface temperature and ensures constant values throughout the application.\u003c\/p\u003e\n\n\u003ch3\u003eIs the stirring rod easy to clean?\u003c\/h3\u003e\n\n\u003cp\u003eYes, the supplied PTFE-coated stirring rod is resistant to chemicals and is easy to clean. The robust metal housing with smooth front panel also makes cleaning quick and safe.\u003c\/p\u003e\n\n\u003cp\u003eHow is overheating prevented?\u003c\/p\u003e\n\n\u003cp\u003eThe integrated SafetyHeat system recognises possible overheating and switches off the heating function automatically. In addition, a clearly visible LED display warns the user as soon as the plate exceeds 40 °C.\u003c\/p\u003e\n\n\u003cp\u003eCan the heating stirrer be used for long-term experiments?\u003c\/p\u003e\n\n\u003cp\u003eThanks to its robust design and reliable temperature stability, this device is also suitable for longer test series. The combination of strong stirrer drive and powerful heating element allows for repeated and consistent results.\u003c\/p\u003e\n\n\u003cp\u003eIs calibration possible?\u003c\/p\u003e\n\n\u003cp\u003eYes, the device has a single-point calibration function for temperature measurement. This makes test series more reproducible, especially when precise absolute temperatures are required for sensitive applications.\u003c\/p\u003e\n\n\u003ch2\u003eConclusion\u003c\/h2\u003e\n\n\u003cp\u003eThis compact laboratory solution offers a convincing combination of safety, durability and efficiency. With its sophisticated design and extensive safety functions, it is ideal for a wide range of applications in biological, chemical and pharmaceutical environments. Its precise heating and stirring performance and ease of use make it an extremely reliable choice for demanding laboratory tasks.\u003c\/p\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n                                                            \u003ctr\u003e\n                            \u003ctd\u003e\n                                Width (magnetic stirrer, agitator):\n\n                            \u003c\/td\u003e\n                             \u003ctd\u003e\n163 mm223 mm\n                            \u003c\/td\u003e\n                        \u003c\/tr\u003e\n                                            \u003ctr\u003e\n                            \u003ctd\u003e\n                                Speed range max.
