Product Description
A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called "flea") immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. Magnetic stirrers often include a hot plate or some other means for heating the liquid.
Magnetic stirrers are often used in chemistry and biology. They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Due to its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants which could contaminate the reaction vessel and the product. They can be used inside hermetically closed vessels or systems, without the need for complicated rotary seals.
On the other hand, the limited size of the bar means that magnetic stirrers can only be used for relatively small (under 4 liters) experiments. They also have difficulty dealing with viscous liquids or thick suspensions.
Efficient Laboratory MixingEngineered for laboratories with a need for reliable liquid mixing, this Magnetic Stirrer excels in blending solutions up to 500 ml. Equipped with a durable stainless steel plate and powerful variable speed control, it ensures uniform results throughout the sample. Its polished surface makes for effortless cleaning and long-lasting use, even under demanding routines.
User-Friendly and Versatile DesignFeaturing a simple interface with adjustable speed settings, operators can adapt the stirring intensity based on specific experimental requirements. The included stir bar streamlines the process, while the units compact profile makes it suitable for both small and large laboratory spaces.
Durable Stainless Steel ConstructionCrafted with high-quality stainless steel, the stirrer not only enhances corrosion resistance, but also maintains a polished appearance. Its robust build supports longevity and dependable service even in busy laboratory environments, making it a practical choice for professionals.
FAQs of Magnetic Stirrer:
