Small laboratory stirring tanks are characterized by their compact size and flexible operation, typically with a capacity ranging from a few liters to several tens of liters, which can meet the needs of small-batch material mixing, reaction or dissolution in laboratories. Their structure is designed to be compact, mostly made of stainless steel, which not only ensures corrosion resistance but also facilitates cleaning and disinfection, meeting the laboratory’s requirements for hygiene and material purity. The stirring system allows flexible adjustment of rotation speed and is equipped with various detachable small blades (such as paddle-type and turbine-type), which can accurately adapt to the mixing needs of materials with different viscosities (such as low-viscosity solutions, suspensions, etc.). The stirring process is stable with high mixing uniformity. In addition, some devices are equipped with small heating/cooling units, temperature and liquid level monitoring instruments, which facilitate real-time control of experimental parameters. They provide a reliable miniaturized simulation environment for experimental work such as formula development and process optimization, making them ideal tools for material property research and process verification in laboratories.
