With a capacity of up to 15 litres and a user-friendly push-button control, these compact devices impress with their robust design and the ability to stir or heat liquids precisely. Compared to similar products on the market, they score points for their durability, sophisticated safety display and attractive price-performance ratio.\u003c\/p\u003e\n\n\u003cp\u003ePerformance features and design\u003c\/p\u003e\n\n\u003cp\u003eThe Guardian 2000 series is characterised by a diverse selection of models for different laboratory equipment and working environments. The most important technical data at a glance:\u003c\/p\u003e\n\n\u003cp\u003e- Different function variants (heating, heating and stirring or stirring only)\u003cbr\u003e\n- Capacity of up to 15 litres for common applications in teaching, research and industrial laboratories\u003cbr\u003e\n- Temperature range between 50 and 500 °C or up to 380 °C for ceramic-coated stainless steel pressure plates\u003cbr\u003e\n- Speed range from 200 to 1600 rpm for the stirrer models\u003cbr\u003e\n- Robust metal housing, choice of ceramic, ceramic-coated stainless steel or resin cover plates\u003cbr\u003e\n- Analogue control for easy operation and reliable adjustment\u003cbr\u003e\n- TÜV-certified safety for professional use\u003c\/p\u003e\n\n\u003cp\u003eThe models have clearly labelled buttons for temperature and speed regulation as well as a conspicuous indicator light that lights up as soon as the hotplate is heated above 40 °C. This warning function increases safety in the laboratory. The outstanding cleaning properties are particularly noteworthy: ceramic surfaces are resistant to chemicals, are easy to clean and enable a clear temperature distribution over the entire heating surface.\u003c\/p\u003e\n\n\u003cp\u003eThe robust metal housing is designed for tough everyday laboratory use. The construction remains intact for a long time even under intensive use. The integrated holder for a stand rod allows accessories such as holders or thermometer rods to be mounted easily. Models are also available that are designed exclusively for stirring and are suitable for sensitive media that do not require heating, for example.\u003c\/p\u003e\n\n\u003ch2\u003eCertifications and standards\u003c\/h2\u003e\n\n\u003cp\u003eAll devices in the Guardian 2000 series are TÜV-certified and therefore meet high safety and quality standards. This certification confirms that both the mechanical stability and electrical safety comply with current guidelines in the laboratory environment. Combined with their robust design, the devices are ideal for long and reliable use.\u003c\/p\u003e\n\n\u003ch2\u003eTypical application examples\u003c\/h2\u003e\n\n\u003cp\u003eThanks to their versatility, the Guardian 2000 analogue hotplates and stirrers can be used in a variety of areas:\u003c\/p\u003e\n\n\u003col\u003e\n\u003cli\u003ePreparation of buffer solutions in research facilities, for example to stabilise protein solutions.  \u003c\/li\u003e\n\u003cli\u003eDissolving and simultaneously heating culture media for cell culture in biotechnological laboratories.  \u003c\/li\u003e\n\u003cli\u003eConcentration of samples for chemical analyses, for example to evaporate organic solvents.  \u003c\/li\u003e\n\u003cli\u003eHomogenisation and temperature control of reaction mixtures for synthetic test series in organic chemistry  \u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eSolvents such as methanol, ethanol or acetone can be handled just as well as aqueous samples under controlled conditions. The uniform heating of temperature-critical liquids can also be realised thanks to the precise heat distribution.\u003c\/p\u003e\n\n\u003cp\u003eFrequently asked questions (FAQ)\u003c\/p\u003e\n\n\u003ch3\u003eWhy is a warning light activated at over 40 °C?\u003c\/h3\u003e\n\n\u003cp\u003eIt is intended to inform the operating personnel in good time about the residual heat of the hotplate. This significantly reduces the risk of burns or damage to the lab bench.\u003c\/p\u003e\n\n\u003cp\u003eWhat are the advantages of the ceramic top version?\u003c\/p\u003e\n\n\u003cp\u003eCeramic surfaces are extremely resistant to chemicals, distribute the temperature more evenly and are easy to clean. This reduces the cleaning and maintenance effort compared to other cover plates.\u003c\/p\u003e\n\n\u003cp\u003eCan I stir sensitive media gently?\u003c\/p\u003e\n\n\u003cp\u003eYes, with the analogue speed controller, stirring speeds can be set from around 200 rpm. In this way, even sensitive samples can be mixed slowly without being foamed up too much or overheated.\u003c\/p\u003e\n\n\u003cp\u003eIs the appliance also suitable for larger volumes of more than 10 litres?\u003c\/p\u003e\n\n\u003cp\u003eThe series is designed for a volume of up to 15 litres. Even with larger volumes of liquid, reliable heating and homogeneous stirring are guaranteed.\u003c\/p\u003e\n\n\u003cp\u003eConclusion\u003c\/p\u003e\n\n\u003cp\u003eThe Guardian 2000 series impresses with its high level of reliability when heating and stirring, proven by TÜV certification, robust technology and intuitive operation. Thanks to various versions, an easy-to-clean top plate and a built-in safety warning, they are a future-proof investment for busy laboratories in educational institutions, research and industry. All models offer excellent value for money, making them an attractive and durable solution for professional laboratory requirements.\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.
